DESCRIPTION OF THE PREFERRFD EM~ODIMENTS
Referring to F'i~s. 1-5, there is shown the therapeutic shoe of this invention generally designated as numeral 10. As depicted in Figs. 1-4, shoe 10 is shown as the insert with the over-structure comprising the conventional top, lacing and undersole not shown for purposes of clarity; it being understood that such over-structural elements will conform to the speciEic type of shoe desired.
Referring specifically to Fig. 1, shoe 10, comprises a top or foot-bearing portion 11, a sole or ground bearing portion 12, a lateral portion 13, a medial portion 14, a heel portion 15, and a raised toe portion 16 for reasons heretnafter more fully explained. Shoe 10 or more accurately ground bearing portion 12 is also formed with a groove or metatarsal split 17 to be more fully discussed hereinafter.
All of said portions and the specific sub-structures forming same are enclosed in a high elastomeric sheathing 18, which stretches at and with the compression and e~tension experienced at the aforesaid respective shoe portions. The bottom portion 18a of 18 may serve as the sole member.
Shoe 10 is sized in relation to the foot intented for its use, but is proportional to the specific size of the foot, and is also specifically designed to the approximate weight of user. As shown in Figs. 1 and 5, the user's foot 20 is disposed within the confines of the lateral, medial and heel portions. The user's toe 21 resides rearwardly of the raised top portion 16 as at interior curved portion 22, and the user's heel 23 resides forwardly of the raised portion 24 of heel portion 15.
mg/~ 5 -3~
~ eferrlng to Figs. 2-4, the internal ~tructuré of shoe 10 is shown ~nd comprises a scarfed or tapered top ruhber member 25 and a bottom scarfed or tapered rubber member 26 which form a wedge-shaped in-ternal configuration 27 which configuration ex-tends from the toe as at 29 to, on the medial side, just beyond the metatarsal region as at _ , and on the lateral side to the end of the heel reclined as at 30.
A plurality of transverse, angled ribs 31 formed of rubber are adhesively secured between members 25 and 26 so as to form a plurality of prism-shaped, air-tight chambers 32. Chambers 32 vary in size, and progressively increase in size from -toe to heel. The ribs 31 may also increase in size, i.e. thickness, from toe to heel. Each chamber is filled with a fluid, customarily a gas such as air under pressure, and the pressure within each chamber generally increases from toe to heel, the thicker ribs being better suited to retain the greater air pressure. Thus concomitantly the heel region chambers are less compressible than the toe region chambers. In the aforesaid manner of construction, the weight of the foot will cause the fore-metatarsal portior to more compressibly yield than the aft-metatarsal portion, thus supporting the foot as well as cushioning same.
In the medial region there is a fluid (e.g. ~ir)-filled, fluid-tight bag 35, formed of thick rubber walls 36. The walls 36 have a limited degree of elasticity so that the high pressure air in the bag 35 will not generally compress with the weight of the foot. Of course the wall 36 strength is determined by the pressure inside the bag 35 and the weight the user exerts on this por-tion. Bag 35 is adjacent to and adhesively sealed with ribs 31 so as to form an integral structure therewith as at 37. The prism-shaped chambers are designed to be more compressible -than the bag 35 mg/'~
c~amber, so -tha-t the weight of the foot in the toe, meta-tarsal heads, and lateral portions proportiona-tely compresses those portions but does not likewise compress the medial bag portion, whereby the effect is to provide a firm arch-support in the medial region while cushioning the foot, particularly so in -the front regions.
The toe region 16 is also of a specialized construction insofar as a thick-walled, fluid-filled, air-tight bag 39, protects and cushions the forward parts of the toes. Bag 39 is sealed to and made integral with member 25, as at 40 and 41.
In another aspect the present invention comprises a metatarsal split integrally formed with and as a part of the shoe construction. Specifically, bottom or sole member 26 is formed wilth transverse Vee-groove 17 wherein the bottom of groove 17 is parallel to and disposed below the meta-tarsal line _ . Sheath 18 overlies this groove 17. In walking,_ ~ogging or running the metatarsal groove 17 provides flexibility, and the shoe is thus a combined therapeu-tic supportive, cushioning and flexible construction.
Referring to Fig. 5, there is shown a schematic outline of the shoe as at 42 with the foot bone structure 43 placed thereon. A line 44 indicates the metatarsal spli-t, and is parallel with the bottom of groove 17 (Figs. 1-3). Circum-scribed region 46 defines the aft toe cushion regions, whil~
circumscribed region 54 defines the compressible toe, metatarsal head, and lateral positions, and region 45 defineY
the relatively non-compressible medial region.
Without wishing to be bound by any theory or mechanism it is believed that the more compressible lateral region in contradistinction to the medial region, and the raised heel portion, permit the correct parts of the foot namely the lateral aspect, m~/ - 7 -` ~ 333 metatarsal heads and di~its to bear the weight in a cushioning manner, while the medial portion forms a supportive arch with the compression or depression of the aforesaid correct positions.
It is also within the contemplation of this invention to provide a specific contour to the foot bearing surface so to provide a mechanical advantage to certain regions such as the anterior compartment of the leg and also posterior muscle group and intrinsic muscle group by allowing the toes to grasp and exercise the leg mucles comfortably. --It is also within the scope of this invention toprovide a dynamic syste~n constituting fluid-filled chambers contained within the sole that redistributes weight automatically upon weight bearing pressure to the portions of the foot best adapted for bearing weight. The parts of the foot structured to bear the body weight are the ]ateral aspect, the fourth and fifth metatarsal shafts, bases and cuboid, and the first, second, third, fourth and fifth metatarsal heads distal to the surgical necks.
In motion, as the weight on different parts of the foot shifts, an automatic cushion of the fluid forms under the excessive weight-bearing segment thereby redistributing the weight. There-fore this dynamic system allows the foot to assume its correct neutral position where weight is on the lateral aspect and meta-ta~sal heads and through the hallux yet it is sufficiently flexi-ble to allow for individual deviations.
It is also within the s~ope of this invention tO in-clude a broader heel base for a firmer, steadier support of the body weight. It may also be described to have a toe box portion forward of and adjacent to the toe portions to eliminate rubbi~g by the toes against the top shoe portion which causes corns and toenail lossO
One preferred embodiment of the present invention is fo the uniform distribution throughout the sole of variably compressi- ~:
ble air-tight, air-filled chambers located between the inside of the shoe and the sole. The air-filled chambers are more compressi-ble laterally than medially so that greater weight bearing will be on the lateral aspect.
Another preferred embodiment of the present invention is a therapeutic shoe having a sole member with a foot bearing portion and an oppositely disposed ground bearing portion which has a transversely disposed groove located below the metatarsal line of the foot. Without wishing to be bound by any theory or mechanism it is believed that this transverse groove thus disposed will allow foreasier dorsiflexion and relieve stress in the muscles of the anterior compartment of the leg. The laces, if any, should also begin, in the top shoe portion, aft the metatarsal split so as not to inhibit dorsiflexion.
To achieve the aforementioned preferred embodiments, ~
the chambers may be of any size or shape as long as the lateral aspect of the shoe is more compressible than the medial aspect.~ ~
Therefore, chambers located laterally may contain more compressible contents or be smaller than chambers located medially. It is also to be understood that chambers may contain any compressible con-tents such as air, sand, gas to attain the desired result.
It is also understood that the invention may be made of any suitable material such as rubber, rubberized fabric, plastic, styrene-butadiene block pol~mers, butyl rubber or any equivalent ¦
v~ G
material.
The present invention may also be covered with any de-sirable material such as canvas, vinyl, leather or cotton.
~6~ 3 The afore-described distal toe region is an optional aspect of the present construction, and it is within the contem-plation of this invention that the shoe lO not be formed with element 3g, but may instead terminate at element 29.
The metatarsal phlan~eal split 17, is in a preferred aspect directly below line 44. 130wever, split 17 may more accura-tely contour the true metatarsal parabola and be slightly arched in this respect.
Raised heel portion 15 is found to relieve stress on the anterior and lateral ~uscular compartments of the leg thereby alleviating fatigue, and relieves stress on the posterior muscles as well.
It is to be borne in mind that the air bag 35 while shown as a sim~le bag construction may nevertheless be constructed as compartments, with sufficient f:Luid pressure to exert a force against the medial portion of the Eoot with compression in the lateral portion. Other materials and construction in addition to fluid-filled bags are also within the cantemplation of this inven-tion. !1 The air-tight chambers can be filled by any desirable means such as pumping contents into the chambers, filling the chambers under pressure or suctioning the contents into the cham-bers. Rubber cement may then be used to seal the chambers.
The shoe of the present invention is use~ul in athleti footwear such as in sneakers, jogging shoes, soccer shoes, ruoby shoes, tennis shoes1 basketball shoes, football shoes, ski boots, climbing boots and the like; as well as in normal walkin~ foot~.ear A particularly preferred use with the present invention is in jogging shoes.
As various other modifications may be made to the ~ 33 present invention as will be known to those skilled in the art, the present invention is not to he construed as being limited to the specific details as heretofore shown and discussed but shall be construed hy the appended claimsu .
whereby the weight of a foot undergoing compression in the lateral and metatarsal portion forms a medial arch.
It is therefore a principal object of this invention to provide new and improved shoe which combines dynamic support and cushioning to the foot.
It is another object of this invention to provide a shoe as aforesaid which maintains the foot in an operable neutral position.
It is another object of this invention to provide a shoe, as immediatel~ aforesaid, which will transfer the weight from one part of the foot to another.
It is still a further object of this invention to pro-vide a shoe insole which dynamically forms an arch in situ with - 3a -the weight distribution of the foot.
It is still a further object of this invention to pro-vide a shoe which will diminish the likelihood of developing cer-tain foot and leg deformities or conditions experienced in running or jogging on hard flat surfaces.
It is still a further object of this invention t~
provide a shoe which will exhibit improved comfort and support to persons having certain ac~uired or congenital deformities or conditions.
It is still a further object of this invention to provide a shoe which provides support and comfort to the foot particularly so in both the metatarsal head and lateral portions, while also providing improved stress relief in the medial ~egion.

The parts of the foot structured to bear the body weight are the ]ateral aspect, the fourth and fifth metatarsal shafts, bases and cuboid, and the first, second, third, fourth and fifth metatarsal heads distal to the surgical necks.
In motion, as the weight on different parts of the foot shifts, an automatic cushion of the fluid forms under the excessive weight-bearing segment thereby redistributing the weight. There-fore this dynamic system allows the foot to assume its correct neutral position where weight is on the lateral aspect and meta-ta~sal heads and through the hallux yet it is sufficiently flexi-ble to allow for individual deviations.
It is also within the s~ope of this invention tO in-clude a broader heel base for a firmer, steadier support of the body weight. It may also be described to have a toe box portion forward of and adjacent to the toe portions to eliminate rubbi~g by the toes against the top shoe portion which causes corns and toenail lossO
One preferred embodiment of the present invention is fo the uniform distribution throughout the sole of variably compressi- ~:
ble air-tight, air-filled chambers located between the inside of the shoe and the sole. The air-filled chambers are more compressi-ble laterally than medially so that greater weight bearing will be on the lateral aspect.
Another preferred embodiment of the present invention is a therapeutic shoe having a sole member with a foot bearing portion and an oppositely disposed ground bearing portion which has a transversely disposed groove located below the metatarsal line of the foot. Without wishing to be bound by any theory or mechanism it is believed that this transverse groove thus disposed will allow foreasier dorsiflexion and relieve stress in the muscles of the anterior compartment of the leg. The laces, if any, should also begin, in the top shoe portion, aft the metatarsal split so as not to inhibit dorsiflexion.
To achieve the aforementioned preferred embodiments, ~
the chambers may be of any size or shape as long as the lateral aspect of the shoe is more compressible than the medial aspect.~ ~
Therefore, chambers located laterally may contain more compressible contents or be smaller than chambers located medially. It is also to be understood that chambers may contain any compressible con-tents such as air, sand, gas to attain the desired result.
It is also understood that the invention may be made of any suitable material such as rubber, rubberized fabric, plastic, styrene-butadiene block pol~mers, butyl rubber or any equivalent ¦
v~ G
material.
The present invention may also be covered with any de-sirable material such as canvas, vinyl, leather or cotton.
~6~ 3 The afore-described distal toe region is an optional aspect of the present construction, and it is within the contem-plation of this invention that the shoe lO not be formed with element 3g, but may instead terminate at element 29.
The metatarsal phlan~eal split 17, is in a preferred aspect directly below line 44. 130wever, split 17 may more accura-tely contour the true metatarsal parabola and be slightly arched in this respect.
Raised heel portion 15 is found to relieve stress on the anterior and lateral ~uscular compartments of the leg thereby alleviating fatigue, and relieves stress on the posterior muscles as well.
It is to be borne in mind that the air bag 35 while shown as a sim~le bag construction may nevertheless be constructed as compartments, with sufficient f:Luid pressure to exert a force against the medial portion of the Eoot with compression in the lateral portion. Other materials and construction in addition to fluid-filled bags are also within the cantemplation of this inven-tion. !1 The air-tight chambers can be filled by any desirable means such as pumping contents into the chambers, filling the chambers under pressure or suctioning the contents into the cham-bers. Rubber cement may then be used to seal the chambers.
The shoe of the present invention is use~ul in athleti footwear such as in sneakers, jogging shoes, soccer shoes, ruoby shoes, tennis shoes1 basketball shoes, football shoes, ski boots, climbing boots and the like; as well as in normal walkin~ foot~.ear A particularly preferred use with the present invention is in jogging shoes.
As various other modifications may be made to the ~ 33 present invention as will be known to those skilled in the art, the present invention is not to he construed as being limited to the specific details as heretofore shown and discussed but shall be construed hy the appended claimsu .
