The specific embodiment
Fig. 1-6 example typical article of footwear 100, its structure is used in walking or promotes the muscle activity of the zones of different of user's health, for example gastrocnemius (calf), musculus quadriceps (thigh) and gluteus maximus (buttocks) when running.When wearing each article of footwear 100, the user keeps poised position usually as possible, and this has promoted bigger muscle activity (with fat combustion optionally).Article of footwear 100 (for example shoes, sandals, boots etc.) comprises footwear top 110 and the base assemblies 200 that is secured on the footwear top 110.Footwear top 110 and base assemblies 200 limit space 120 together, and this space 120 makes up the pin that is used for firmly and cosily holding the people.Although shoes are depicted as typical article of footwear 100, this base assemblies 200 can be used for the article of footwear of other types, includes, but are not limited to boots, sandals, slippers (flip-flop) etc.
(for example passing through adhesive) can be sewed up and/or glue together on base assemblies 200 in footwear top 110.Footwear top 110 can be suitable for receiving and holding the material structure of user's pin by one or more leathers, fabric, non-textile material and any other.In some instances, footwear top 110 comprises moisture absorption (moisture-wicking) material.
Referring to Fig. 7-15, base assemblies 200 provides trickle unstability, the health that impels the user with respect to usually stably base assemblies adapt to and keep the balance gait more hardy, thereby promote muscle activity.Referring to Fig. 3-10, base assemblies 200 has preceding foot 202 and heel 204, and comprises outer bottom 210 and midsole 220.Each has separately preceding foot 212,222 and heel separately 214,224 outer bottom 210 and midsole 220, and they are corresponding to the preceding foot 202 and the heel 204 of base assemblies 200.In some instances, for example among Figure 10,14 and 15, outer bottom 210 has the thickness T 0 of between about 3mm and about 7mm (preferably about 5mm), and midsole 220 has at approximately 3mm and approximately the thickness T m of (preferably about 13mm) between the 20mm.Outer bottom 210 can be made by natural rubber, is perhaps formed by rubber compound, comprises isobutene rubber, butadiene rubber, styrene butadiene rubber and/or natural rubber.Outer bottom 210 has at approximately 40ShoreA and the approximately hardness of (preferably 50ShoreA) between the 70ShoreA.Midsole 220 can (EVA) be made by polyurethane or ethylene vinyl acetate (ethylene vinyl acetate), and has the hardness that (is preferably between about 60Shore A and the about 65Shore A) between 50Shore A and the about 70Shore A approximately.
Base assemblies 200 comprises unstable insert 230, and it is arranged in fact between outer bottom 210 and the midsole 220, in the preceding foot 202 of base assemblies 200.This instability insert 230 produces forward foot in a step projection 216 (for example protuberance protuberance) lightly in outer bottom 210, make the user experience slight waving (while front and back and/or arrive) in the preceding foot 202 of base assemblies.In some instances, the preceding foot 212 of outer bottom 210 limits at approximately 130mm and the approximately radius of curvature R of (preferably about 160mm) between the 190mm.This forward foot in a step projection 216 can have the height H of at about 4mm and approximately the 12mm (preferably approximately 8mm) of outward flange 218 from the minimum point amount of projection 216 to outer bottom 210.Usually, the experience when ining contrast to the stable traditionally shoes of dress, the user applies relative more energy to keep balance and to overcome the unstability that unstable insert 230 causes.
In some embodiments, unstable insert 230 limits oval in shape in top view and side view, as shown in Fig. 8,10 and 13.In some instances, unstable insert 230 has the thickness T i of between about 3mm and 9mm (preferably about 6mm), at the length L i of about 65mm to (preferably about 76mm) between about 85mm, and at approximately 45mm and approximately the width W i of (preferably about 50mm) between the 55mm.In some applications, unstable insert 230 is provided with like this, makes 205 one-tenth on the transverse axis of longitudinal axis 235 and base assemblies 200 of unstable insert 230 angle beta of (preferably about 20 °) between about 10 ° and about 30 °.This instability insert 230 can be made by polyurethane, and has the hardness that (is preferably between about 15Asker C and the about 20Asker C) between 10Asker C and the about 25Asker C approximately.By making unstable insert 230 have softer hardness with respect to outer bottom 210 and midsole 220, the user experiences unstable insert 230 at first based on contacting and the unstability of the forward foot in a step projection 216 that causes between outer bottom 210 and the ground.When the user is sent to its weight on the shoes 100, unstable insert 230 flattens between outer bottom 210 and midsole 220 at least in part, thereby when shoes 100 bear user's weight, flatten (preferably fully flattening) forward foot in a step projection 216 at least in part, and allow the user to experience in the preceding foot 202 of base assemblies, to increase or stability substantially completely.Therefore, advance from the teeth outwards (for example walk or run) when the user wears a pair of shoes 100, in the time of on its weight being sent to wherein footwear 100, the user experiences initial amphibolia, then when each footwear 100 bear at least some weight of user, enter stationary phase.For example, when receiving the thresholding load of 30lbs at least, unstable insert 230 is crushed, thereby flattens forward foot in a step projection 216 (for example such outer bottom 210 has the radius of curvature R that reduces relatively).Unstable insert 230 can make up equally and be used for flattening under other thresholding loads or squeeze flat (for example 15lbs, 50lbs etc.) at least, thus some user's weight group as applicable object.Initial amphibolia, cause that the user uses stable muscle, and apply more energy with respect to traditional footwear.Usually do not need completely unstable footwear, the functional and safe footwear of training usefulness are provided for the user stationary phase after slight so at least unsettled period.
In some embodiments, base assemblies 200 is included in the root insert 240 in the heel 204 of base assemblies 200, and it is arranged in fact between outer bottom 210 and the midsole 220.Shown in Fig. 9-12 and 15, this heel insert 240 can be made by polyurethane or polyolefin, ethylene vinyl acetate (ethylene-vinyl-acetate) copolymer (EVA) for example, and/or have at about 25Asker C and about between the 55Asker C hardness of (be preferably in about 42Asker C and approximately between the 48Asker C).Heel insert 240 can have at approximately 10mm and approximately the thickness T h (Figure 15) of (preferably about 25mm) between the 35mm.This heel insert 240 not only provides buffering and comfortableness for the user, and with respect to outer bottom 210 and midsole 220, the hardness of softer relatively heel insert 240 allows the heel 204 of base assemblies 200 to flatten at least partly under user's weight, thereby causes that the user shifts its weight towards the preceding foot 202 of base assemblies 200.When the user transfers to its weight in the preceding foot 202 of base assemblies 200, the slight unstability (causing) of foot 202 before the user experiences by forward foot in a step projection 216, and apply relative more energy and/or use more relatively muscle to keep balance.When forward foot in a step projection 216 was flattened owing to user's weight transmission or sunk, the user experienced stationary phase subsequently.
Article of footwear 100 can comprise and be secured to the pin bed 300 (Fig. 6) at the end 130 in shoes assembly 200 and/or the footwear that the end 130 is in the space 120 that limits by top 100 and shoes assembly 200 in these footwear.This pin bed 300 conformably meets and represents the shape of user's sole and outer bottom 100.Pin bed 300 can be a foam piece, has braiding or non-woven fabric and covers this foam piece.
A plurality of embodiments have been described.In any case, it will be appreciated that under the situation that does not break away from the spirit and scope of the present invention, many distortion to be arranged.Correspondingly, other embodiments are all within the scope of the claim of back.
