- Front portion 2 is defined as the portion of the sole extending from the front of the shoe to the straight line L 1 represented in dots in FIGS. 1 and 2 , substantially corresponding to the position of studs 5 b , the rear-most studs of the plurality of studs 5 .

- Front portion 2 is a portion with low thickness, i.e. a thickness of some millimeters (mm), preferentially less than 10 mm, with a constant and substantially flat thickness. Front portion 2 may comprise, from the origin, a slight bending raising the front of front portion 2 with relation to the rear of front portion 2 so as to arrange maximum support with the ground during the digitigrade phase, i.e. the period when walking or running when the foot support is above the forefoot.
- mm millimeters
- Front portion 2 is the portion of sole 1 supporting the forefoot and more precisely the anterior transverse arch and the anterior supports essentially formed by the head of the first metatarsal and the plantar face of the big toe.
- Rear portion 3 of the outer sole 1 is formed by a rigid upper shell 3 a in contact with the instep 11 and by a riser 4 at the lower portion in contact with the ground, riser 4 comprising a first flat portion 4 a at the level of the rear portion 3 and a second portion 4 b extending into the central portion 8 of sole 1 .
- Upper shell 3 a comprises a thickness that is substantially constant and substantially equivalent to the thickness of the front portion 2 .
- This upper shell 3 a is made in a plastic material, preferably rigid and of the thermoplastic or thermohardening type, possibly reinforced by nylon, glass or other type fibers, and forms a flat support at the level of its upper face 3 c.
- the upper shell 3 a may also extend laterally so as to form an enveloping shell 3 b to optimize the maintenance and rigidity of shoe 10 .
- riser 4 is overmolded onto the upper shell 3 a .
- Riser 4 is preferentially a visible outer overmolding, whose thickness is constant along rear portion 3 , the thickness may be between 1 and 25 mm.
- riser 4 will have a thickness of between 10 and 15 mm in order to sufficiently raise the rear portion with relation to the front portion 2 .
- Riser 4 substantially has the shape of a solid heel piece, i.e., a heel piece without any external recesses, at least in its front portion 4 b and comprises a flat outer surface 12 , this surface 12 enabling a stable support of the heel when in contact with the ground when studs 5 and 6 are inserted in the ground.
- the riser 4 extends, in its portion 4 b , into central portion 8 of sole 1 .
- the thickness of riser 4 is beveled along a substantially convex profile 13 such that riser 4 maintains and reinforces the rear portion of the central portion 8 , thus reconditioning the configuration of the mid-foot supports.
- Portion 4 b of the riser enables this area of the central portion 8 to be reinforced by providing additional support in the mid-foot support.
- Central portion 8 of sole 1 presents an outer surface profile 14 (i.e.: the outer plantar face) that is curved and arch shaped that forms the outer longitudinal curvature of the shoe. This outer longitudinal curvature is accentuated by the difference in level created by riser 4 in the rear portion 3 . Profile 13 of portion 4 b of riser 4 also accentuates this arch-shaped curvature of the outer profile 14 of central portion 8 of sole 1 .
- Central portion 8 of sole 1 presents an inner surface profile 16 (i.e.: the inner plantar face) that is also curved and arch shaped that forms the inner longitudinal curvature of the shoe.
- the curvature of the inner surface profile 16 varies along the transverse axis of the shoe in order to follow the shape of the mid-foot longitudinal arch and to adequately support it.
- internal profile 16 a of this inner surface profile 16 presents greater arching than its external profile 16 b while the internal arch of the mid-foot comprises greater arching than that of its external arch.
- Riser 4 is typically made of a polymer material determined by the manufacturer for the purpose of providing an additional characteristic to the sports shoe 10 .
- Riser 4 may be formed by overmolding a mixture of several materials in order to provide different properties to the outer sole 1 . Therefore, riser 4 both raises in an isolated manner the rear portion 3 with relation to the front portion 2 but also provides, by strategically and cleverly choosing a material or mix of materials, additional properties of stability, cushioning, shock wave and/or vibration absorption or else properties of elasticity or return.
- riser 4 may be made of a slightly flexible and deformable material, such as a reticulated foam, so as to procure a cushioning function to shoe 1 .
- the riser may also comprise air bubbles and/or springs in order to further improve this cushioning function.
- Central portion 8 may also be made of a material different from front portion 2 and upper shell 3 a of rear portion 3 in order to provide an additional technical characteristic to the sports shoe, such as for example better stability, particularly in torsion, between front portion 2 and rear portion 3 by the utilization of a plastic material that is more rigid than the material of the outer sole 1 or by adding an intermediate shell or an additional tongue, increasing the lateral rigidity of the assembly.
- such a shoe comprising a rear raising isolated on the rear of the outer sole (i.e., not continuous over the entire length of the shoe) controlling a natural curvature effect of the shoe, does not present the disadvantages inherent to shoes with thick soles (i.e., also filling in the mid-foot) in which said sole limits the proprioceptive role of the foot and needlessly weighs down the shoe.
- This natural curvature here is accentuated by the particular shape of the central portion and by that of the riser whose arrangement enables both an inner profile proposing a curvature positioning the foot in a natural position and an outer profile in the shape of an arch providing cushioning and static and dynamic support to the mid-foot.
- the internal and external longitudinal curvatures enable the longitudinal arches of the foot to be better contained and enveloped, thus increasing the bearing surface of the plantar supports, limiting the fatigability of the sports player.
- the loads and pressures on the foot are then better distributed, thus improving, when walking and/or running:
- the particular curvature of the central portion preserves the biomechanical activity of the arches of the mid-foot in order to optimize the physiological qualities of the foot in its entirety, i.e., stability, absorption, elasticity, propulsion and drainage.
- the outer positioning of the riser ensures a true posterior raising of the heel of the shoe, creating a difference in level between the rear portion and the front portion without modifying the inner volume of the instep and without weighing down the shoe.
- This outer positioning also reconditions the location of the shod foot in a more harmonious and more physiological posture by allowing the foot to naturally find the best supported and best enveloped internal and external longitudinal arches.
- the raising isolated in the rear portion reinforces the grip with the ground initially intended by shoes with studs, particularly in terms of support and acceleration.
- the posterior riser is solid (i.e., it does not comprise any openings or outer recesses), and its outer surface, capable of being in contact with the ground when the studs are pushed into the ground, is flat over the entire rear portion of the shoe.
- this sports shoe enables a stable posterior support and effective and homogeneous raising over the rear portion when the studs are pushed into soft ground.
- the shoe is thus differentiated from existing sports shoes, and notably from those comprising additions of material isolated at the level of each posterior stud that offer insecure posterior support caused by sinking of the raised isolated portions of the studs. In fact, on soft ground, the soil tends to fill in all of the recesses found between the posterior studs, creating an ineffective raising of the heel and an unstable support.

Abstract
A sports shoe includes an instep and a rigid outer sole, the sole having a front portion including a first plurality of studs, a central portion, and a rear portion including a second plurality of studs. The rear portion includes a thickened portion with a flat outer surface on which the second plurality of studs is located, the thickened portion raising the rear portion relative to the front portion; the central portion includes an inwardly curved outer profile.
Description
- The present invention relates to a sports shoe with studs comprising a rigid sole notably for playing soccer, rugby or other sports.
- For sports players and especially for soccer players, the foot is an essential asset when playing sports. Two soccer players may be differentiated by the quality of their passes or kicks, technique being likely to be more important in one than in the other.
- From this perspective of improving player performance, manufacturers have developed shoes enabling, for example, ball feel, ball strike quality or else stability by adequate ground/shoe grip to be influenced and/or improved.
- Expansion of the economic environment and ongoing research in view of new levels of performance for the sports player, particularly for the soccer player, require the player to increase the frequency and intensity of training and matches, i.e., an increase in the distances covered per match and per week.
- Paradoxically, shoes with studs, particularly for playing soccer, have not changed much over these last few years in response to new requirements in the distances covered by the players.
- In comparison, shoes utilized in other sports disciplines and particularly in disciplines in which great distances are covered, such as running or basketball, have seen constant changes to meet the expectations of sports players.
- As an illustration, in the case of running, many shoe models enable the expectations of each runner to be specifically met and enable training and/or long-distance races to be performed with less physical fatigue. Therefore, supination shoes, pronation shoes, training shoes with a stronger sole, very light shoes for competing, etc., may be found.
- In this context, the invention aims to provide a sports shoe with studs providing adequate engagement with the long distances covered by the sports player during training and matches in order to relieve and/or preserve his health.
- For this purpose, the invention proposes a sports shoe comprising an instep and a rigid outer sole, said sole presenting:
-
- a front portion comprising a first plurality of studs;
- a central portion;
- a rear portion comprising a second plurality of studs;
- said shoe being characterized in that:
-
- said rear portion comprises a thickened portion presenting a flat outer surface on which said second plurality of studs is located, said thickened portion raising said rear portion with relation to said front portion; and in that
- said central portion comprises a curved outer profile.
- Raising is understood to refer to a modification in the height of a first plane with relation to a second plane substantially parallel to the first plane and tangent to the front portion of the shoe.
- The invention therefore proposes a sports shoe with studs, particularly for playing soccer, rugby or other sports, ensuring a posterior raising of the heel of the shoe, enabling insidious and recurring mechanical pathologies in the sports player due to current requirements to be reduced.
- In fact, the shoe according to the invention reduces the functional overload of the posterior muscle chain and particularly of the extensor system for better distribution of the load of the foot in the shoe, therefore limiting muscle tension and injury to the dependent muscles, tendons, ligaments and joints.
- In fact, this functional disequilibrium of the extensor system promotes, in the sports player, the regular onset of mechanical articular, muscular, tendinous, aponeurotic or else ligamentary pathologies at the level of the foot, knee, lower limbs, pelvis and back.
- The posterior difference in level of the shoe enables the foot/shoe assembly to be harmonized by considerably improving the work of the extensor system. Thanks to the invention, the foot performs functional work in synergy between the posterior drive chain and the dependent crossed and anterior muscle chains.
- The longitudinal curvature of the shoe resulting from the posterior difference in level enables the longitudinal arches of the foot to be reliably covered. This central curvature promotes the proprioceptive stability of the arches of the foot and elastic cushioning of the mid-foot.
- Therefore, the sports shoe according to the invention reduces the onset of all of these pathologies by:
-
- improving the static positioning of the sports player in a reference position that is physiologically the most neutral possible position;
- rebalancing the ongoing traction work of the extensor system, reducing physical fatigue;
- optimizing the rebalancing of all postural and static problems;
- reducing the overload of the posterior chain by harmonizing the muscle work on all the muscle chains;
- improving muscle yield and corresponding muscle performance by limiting the risk of injury.
- In addition to the principal characteristics that have just been mentioned in the previous paragraph, the sports shoe with studs according to the invention may comprise one or more of the characteristics below, considered individually or according to all technically feasible combinations:
-
- said central portion comprises an arch-shaped curved inner profile, said inner profile being able to follow the shape of the longitudinal arch of the mid-foot;
- the curve of said inner profile of said central portion varies along the transverse axis of the shoe;
- said inner profile of said sole presents an internal profile and an external profile forming a transverse arch, said internal profile comprising greater arching than said external profile;
- said outer profile of said central portion forms the outer longitudinal curvature of said shoe;
- said central portion is an elastic portion able to be deformed to cushion said foot;
- said thickened portion is between 1 and 25 mm;
- said thickened portion is between 10 and 15 mm;
- said thickened portion of said posterior portion extends in said central portion to reinforce the rear portion of said central portion;
- said thickened portion extending in said central portion comprises a
- beveled portion along a convex profile;
- said thickened portion is formed by a removable riser;
- said outer sole comprises means to form an integral connection with said removable riser;
- said studs are removable studs screwed onto said outer sole so as to form an integral connection with said removable riser;
- said studs are molded studs or screwed studs forming an integral connection with said removable riser;
- said thickened portion forms an integral connection with the rear portion of said outer sole;
- said studs are studs molded onto said outer sole.
- Another object of the present invention is a removable riser characterized in that the riser comprises an upper surface able to cooperate with the outer surface of the outer sole of a sports shoe according to the invention.

Shoe 10, in conformance with the first embodiment of the invention and illustrated in particular inFIGS. 1 and 2 , comprises a rigid outer sole 1 extending from the front to the rear of theshoe 10 and forming an integral connection with aninstep 11. - Rigid sole is understood to refer to a sole that, in contrast to a flexible sole, typically a sole for a running shoe, does not accompany the folding movement from the forefoot to the toes when walking or running.
- In a known manner, the
instep 11 is able to receive and overlap theentire foot 100. Theinstep 11 is made by means of several flexible pieces of leather, cloth or any other synthetic material known to the person skilled in the art. - The outer sole 1 comprises three distinct parts, each fulfilling a role in maintaining and positioning the
foot 100 in the shoe: -
- a
first portion 2 situated in the front supporting the forefoot, subsequently called thefront portion 2; - a
second portion 3 situated at the rear supporting the heel, subsequently called therear portion 3, and; - a third
central portion 8 for supporting the mid-foot.
- a
- Each portion is defined and sized in order to form an overall
plantar profile 15 proposing the most naturalpossible foot support 100, therefore preserving the anatomical and biomechanical balance of the sports player. - The outer sole 1 comprises a plurality of
studs front portion 2 andrear portion 3 of the outer sole 1. Preferentially, therear portion 3 comprises fourstuds 6, and thefront portion 2 comprises at least fourstuds 5. - In general, a stud is defined as an element, generally a protuberance, lining the sole of some types of sports shoes in order to ensure better adhesion with the ground, and particularly with soft or grassy ground.
- Therefore, stud is also considered to be different elements known to the person skilled in the art ensuring better adhesion with the ground, in particular known by various names: bar, blade, etc.
- In this first embodiment of the invention,
studs - In a variation, these studs may be screwed studs in a plastic or metallic material.
-
Studs - The outer sole 1 assembly, here including molded
studs -
Front portion 2 is defined as the portion of the sole extending from the front of the shoe to the straight line L1 represented in dots inFIGS. 1 and 2 , substantially corresponding to the position ofstuds 5 b, the rear-most studs of the plurality ofstuds 5. - The
rear portion 3 extends from straight line L2 represented in dots in these sameFIGS. 1 and 2 , substantially corresponding to the position ofstuds 6 a, the most forward of the plurality ofstuds 6 to the rear of the shoe. -
Central portion 8 is the portion extending betweenfront portion 2 andrear portion 3, i.e., between straight lines L1 and L2. -
Front portion 2 is a portion with low thickness, i.e. a thickness of some millimeters (mm), preferentially less than 10 mm, with a constant and substantially flat thickness.Front portion 2 may comprise, from the origin, a slight bending raising the front offront portion 2 with relation to the rear offront portion 2 so as to arrange maximum support with the ground during the digitigrade phase, i.e. the period when walking or running when the foot support is above the forefoot. -
Front portion 2 is the portion of sole 1 supporting the forefoot and more precisely the anterior transverse arch and the anterior supports essentially formed by the head of the first metatarsal and the plantar face of the big toe. -
Rear portion 3 of the outer sole 1 is formed by a rigidupper shell 3 a in contact with theinstep 11 and by ariser 4 at the lower portion in contact with the ground,riser 4 comprising a firstflat portion 4 a at the level of therear portion 3 and asecond portion 4 b extending into thecentral portion 8 of sole 1. -
Upper shell 3 a comprises a thickness that is substantially constant and substantially equivalent to the thickness of thefront portion 2. Thisupper shell 3 a is made in a plastic material, preferably rigid and of the thermoplastic or thermohardening type, possibly reinforced by nylon, glass or other type fibers, and forms a flat support at the level of itsupper face 3 c. - According to a variation of this first embodiment illustrated in
FIG. 3 , theupper shell 3 a may also extend laterally so as to form an envelopingshell 3 b to optimize the maintenance and rigidity ofshoe 10. - In general, in this first embodiment represented in
FIGS. 1 , 2 and 3,riser 4 is overmolded onto theupper shell 3 a.Riser 4 is preferentially a visible outer overmolding, whose thickness is constant alongrear portion 3, the thickness may be between 1 and 25 mm. Preferably,riser 4 will have a thickness of between 10 and 15 mm in order to sufficiently raise the rear portion with relation to thefront portion 2. -
Riser 4 substantially has the shape of a solid heel piece, i.e., a heel piece without any external recesses, at least in itsfront portion 4 b and comprises a flatouter surface 12, thissurface 12 enabling a stable support of the heel when in contact with the ground whenstuds - The
riser 4 extends, in itsportion 4 b, intocentral portion 8 of sole 1. In thiscentral portion 8, the thickness ofriser 4 is beveled along a substantiallyconvex profile 13 such thatriser 4 maintains and reinforces the rear portion of thecentral portion 8, thus reconditioning the configuration of the mid-foot supports. -
Portion 4 b of the riser enables this area of thecentral portion 8 to be reinforced by providing additional support in the mid-foot support. -
Central portion 8 of sole 1 presents an outer surface profile 14 (i.e.: the outer plantar face) that is curved and arch shaped that forms the outer longitudinal curvature of the shoe. This outer longitudinal curvature is accentuated by the difference in level created byriser 4 in therear portion 3.Profile 13 ofportion 4 b ofriser 4 also accentuates this arch-shaped curvature of theouter profile 14 ofcentral portion 8 of sole 1. -
Central portion 8 of sole 1 presents an inner surface profile 16 (i.e.: the inner plantar face) that is also curved and arch shaped that forms the inner longitudinal curvature of the shoe. - The curvature of the
inner surface profile 16 varies along the transverse axis of the shoe in order to follow the shape of the mid-foot longitudinal arch and to adequately support it. - Thus,
internal profile 16 a of thisinner surface profile 16 presents greater arching than itsexternal profile 16 b while the internal arch of the mid-foot comprises greater arching than that of its external arch. -
Riser 4 is typically made of a polymer material determined by the manufacturer for the purpose of providing an additional characteristic to thesports shoe 10.Riser 4 may be formed by overmolding a mixture of several materials in order to provide different properties to the outer sole 1. Therefore,riser 4 both raises in an isolated manner therear portion 3 with relation to thefront portion 2 but also provides, by strategically and cleverly choosing a material or mix of materials, additional properties of stability, cushioning, shock wave and/or vibration absorption or else properties of elasticity or return. - Therefore for example,
riser 4 may be made of a slightly flexible and deformable material, such as a reticulated foam, so as to procure a cushioning function to shoe 1. The riser may also comprise air bubbles and/or springs in order to further improve this cushioning function. -
Central portion 8 may also be made of a material different fromfront portion 2 andupper shell 3 a ofrear portion 3 in order to provide an additional technical characteristic to the sports shoe, such as for example better stability, particularly in torsion, betweenfront portion 2 andrear portion 3 by the utilization of a plastic material that is more rigid than the material of the outer sole 1 or by adding an intermediate shell or an additional tongue, increasing the lateral rigidity of the assembly. - Therefore, such a shoe comprising a rear raising isolated on the rear of the outer sole (i.e., not continuous over the entire length of the shoe) controlling a natural curvature effect of the shoe, does not present the disadvantages inherent to shoes with thick soles (i.e., also filling in the mid-foot) in which said sole limits the proprioceptive role of the foot and needlessly weighs down the shoe.
- This natural curvature here is accentuated by the particular shape of the central portion and by that of the riser whose arrangement enables both an inner profile proposing a curvature positioning the foot in a natural position and an outer profile in the shape of an arch providing cushioning and static and dynamic support to the mid-foot.
- The internal and external longitudinal curvatures enable the longitudinal arches of the foot to be better contained and enveloped, thus increasing the bearing surface of the plantar supports, limiting the fatigability of the sports player. The loads and pressures on the foot are then better distributed, thus improving, when walking and/or running:
-
- the transmission of forces and loads from the hindfoot to the mid-foot by limiting tension stresses on the entire posterior muscle chain,
- flexible cushioning and return of the weight transmitted by the tibia to the forefoot, thus facilitating rapid accelerations and starts.
- Therefore, the particular curvature of the central portion, particularly created by the riser, preserves the biomechanical activity of the arches of the mid-foot in order to optimize the physiological qualities of the foot in its entirety, i.e., stability, absorption, elasticity, propulsion and drainage.
- The outer positioning of the riser ensures a true posterior raising of the heel of the shoe, creating a difference in level between the rear portion and the front portion without modifying the inner volume of the instep and without weighing down the shoe.
- This outer positioning also reconditions the location of the shod foot in a more harmonious and more physiological posture by allowing the foot to naturally find the best supported and best enveloped internal and external longitudinal arches. The raising isolated in the rear portion reinforces the grip with the ground initially intended by shoes with studs, particularly in terms of support and acceleration.
- In addition, the posterior riser is solid (i.e., it does not comprise any openings or outer recesses), and its outer surface, capable of being in contact with the ground when the studs are pushed into the ground, is flat over the entire rear portion of the shoe.
- Thus, this sports shoe enables a stable posterior support and effective and homogeneous raising over the rear portion when the studs are pushed into soft ground. The shoe is thus differentiated from existing sports shoes, and notably from those comprising additions of material isolated at the level of each posterior stud that offer insecure posterior support caused by sinking of the raised isolated portions of the studs. In fact, on soft ground, the soil tends to fill in all of the recesses found between the posterior studs, creating an ineffective raising of the heel and an unstable support.

FIG. 6 represents asports shoe 50 in conformance with a second embodiment of the invention. -
Shoe 50 comprises, unless otherwise stated, all the characteristics ofsports shoe 10 described above. - In this
shoe 50, unlikeshoe 10,riser 54 of therear portion 56 of the outer sole 58 is removable. - This
removable riser 54 comprises anupper surface 53 capable of cooperating with theouter surface 63 of outer sole 58. -
Riser 54 also comprises a flatouter surface 52, thissurface 52 enabling a stable support of the heel during contact 20 with the ground whenstuds Riser 54 forms an integral connection with outer sole 58 by screwing of theposterior studs 51 that each comprise a screwedrod 60. - Screwed
rods 60 traverse the corresponding bores 62 disposed inriser 54 and are screwed inside threaded bores 61 disposed in the outer sole 58. - Screwed
rods 60 are sized so as to be able to maintainriser 54 in compression betweenstuds 51 and outer sole 58 when thesestuds 51 are screwed onto this outer sole 58. - The length of the screwed
rods 60 ofstuds 51 is of course a function of the thickness of theriser 54 used. - According to a first variation that is not represented, the bores inserted into the outer sole 58 are preconfigured so as to be able to receive, regardless of the thickness of the
riser 54 used, the same screwedrods 60. - According to a second variation that is not represented, screwed
rods 60 are screwed both insideriser 54 by means of threaded bores and inside threaded bores 61 disposed in outer sole 58. - According to a third variation that is not represented,
studs 51 are either screwed intoriser 54 or thermobonded toriser 54. Theremovable riser 54 forms an integral connection with other engaging means able to receive and form an integral connection withremovable riser 54 on the outer sole 58 of the shoe. - By way of example,
riser 54 will be placed on and form an integral connection with outer sole 58 by screwing, clipage, interlocking, socketing, lateral or longitudinal sliding or by any other type of equivalent means enabling a removable riser to be simply and rapidly connected/disconnected to or from an outer sole of a shoe. -
FIG. 8 represents a variation of an embodiment ofshoe 50 according to the second embodiment of the invention. In this variation, riser 54 a comprises a projecting slider 82 (male portion) in its upper portion enabling riser 54 a to be placed by longitudinal sliding in a hollow slider 81 (female portion) present in outer sole 1. -
FIG. 9 represents another variation of embodiment ofshoe 50 according to the second embodiment of the invention. In this variation,riser 54 b comprises at the level of itsupper surface 53non-piercing cavities 92 as well as abore 62′. Theouter surface 63 of outer sole 58 compriseslugs 91 able to follow the shape ofcavities 92 and able to be inserted into saidcavities 92 whenriser 54 b is placed onshoe 50.Lugs 91 andcavities 92 enable a bearing surface or additional retention ofriser 54 b to be made and positioned. In this variation,riser 54 b forms an integral connection onshoe 50 for example by means of aquarter screw 83 enabling the rapid screwing or unscrewing ofriser 54 b by means of a simple element that is able to be inserted intoslot 84 of thequarter screw 83. -
FIG. 10 represents another variation of embodiment ofshoe 50 according to the second embodiment of the invention. In this variation,riser 54 c is associated with the outer sole 58 by aquarter engaging system 93 with the socketing and rotation ofriser 54 c.Riser 54 c also comprises fixation means 94 able to prevent unwanted rotation ofriser 54 c in order to secure it in a good position. -
FIG. 11 represents another variation of embodiment of the shoe according to the invention. In this variation,front portion 4 b ofriser 54 d is inserted into anotch 85 preconfigured in the outer sole 58 used as an anti-sliding stop. Theupper surface 53 ofriser 54 d comprises retention lugs 86 able to be inserted intobores 87 of the outer sole 58 enablingriser 54 d to be positioned onto sole 58. -
Riser 54 d is removably connected by screwing ascrew 88 into a threadedbore 89 inside sole 58. - According to the variations described,
posterior studs 51 may either be studs screwed into the outer sole 58 or studs screwed intoriser riser - According to another variation illustrated in
FIG. 7 , removable riser 54 e provides a raising at the level of therear portion 3 and at the level of thecentral portion 8 of outer sole 58. - Removable riser 54 e may partially or fully cover
central portion 8 of sole 58 (FIG. 7 illustrates the case where removable riser 54 e fully covers central portion 8). - The portion of riser 54 e situated in
central portion 8 and the portion of riser 54 e situated inrear portion 3 of sole 58 may be made with different types of materials contributing different qualities such as cushioning and stability qualities or the absorption of shock waves harmful to the integrity of cartilage or else the absorption of vibrations which generate various mechanical pathologies. - In this variation, riser 54 e is removably connected onto outer sole 58 by an engaging means such as described in the previous figures.
- The removable aspect of the riser has been particularly described with a sports shoe comprising an outer curved sole in its central portion, i.e., at the level of the mid-foot. However, it is also planned to be able to use a removable riser such as described in the present application on a sports shoe sole that does not comprise a curvature at the level of its central portion.
- The removability of
riser 54 enables the type of riser to be quickly and easily interchanged in view of contributing a new technical characteristic to the shoe and/or to modify the shoe, such as for example the modification of the riser height. Changing the height of the posterior raising, by the rapid interchangeability ofriser 54, thus enables achangeable sports shoe 50 with studs to be proposed that can be adapted to various technical and anatomical requirements of the sports players. -
Riser 54 may then comprise different visible outer markings in order to identify the different types of risers, such as for example a color code corresponding to different thicknesses.Riser 54 may also be made of different materials providing qualities in addition to the raising ofshoe 50, such as for example cushioning and stability qualities, the absorption of shock waves harmful to the integrity of cartilage or else the absorption of vibrations which generate various functional pathologies in the sports player. - According to another variation of embodiment that is not represented,
riser 54 is a “composite” riser, the riser comprises a plurality of layers, of low thickness, on the order of some millimeters, made by means of different materials comprising specific and different mechanical properties. Thus,riser 54 becomes an element that can be entirely and unlimitedly customized, adjusted and perfected, either regarding the thickness or the mechanical properties that it contributes to the sports shoe, thus enabling the criteria, expectations and needs of the sports player to be met as closely as possible. - The sports shoe according to the invention thus constitutes an elementary link in the prevention, protection and improvement of sports player performance.
- The sports shoe also presents the following additional advantages:
-
- no modification in the volume of the existing instep, which leads to a low development cost and allows the use of the instep volume for adapting custom made plantar orthotics;
- preservation of the biomechanics of the lower limbs, pelvis and back;
- improvement and respect of the three arches and three supporting pillars of the foot;
- improvement in the effort venous system and improvement in plantar venous drainage and lower limb drainage;
- improvement in explosiveness on rapid races from a standing start;
- improved comfort;
- protection against and control of mechanical pain;
- improvement in toxin elimination;
- improved performance and muscle yield; and
- limited risk of injury.
- It goes without saying that other modes of embodiment may be contemplated without departing from the scope of the invention, this in no way being limited to the examples described and represented.
- In particular, although the modes of embodiment described previously apply to a soccer shoe, the invention may also relate to shoes provided for playing other sports such as rugby, American football, baseball or other sports.
