A strobel for an article of footwear includes a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around at least a portion of a perimeter of the interior cavity. A first bond secures opposing inner surfaces of the polymeric bladder to one another and extends transversely inward from a medial side of the peripheral flange only partway transversely across the interior cavity. A second bond is rearward of the first bond. The second bond extends transversely inward from a lateral side of the peripheral flange only partway transversely across the interior cavity. A tensile component is disposed in the interior cavity. An outer edge of the tensile component extends transversely inward at and borders a perimeter of the first bond and a perimeter of the second bond.

An article of footwear includes a strobel, a footwear upper, and a sole plate. The strobel includes a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around a perimeter of the interior cavity from a medial side to a lateral side of the polymeric bladder at a front of the polymeric bladder. The footwear upper is secured to the peripheral flange. The sole plate has a heel portion, a midfoot portion, and a forefoot portion, and a rear extent of the strobel is secured to the sole plate or to the footwear upper forward of a rear extent of the sole plate. A method of manufacturing the article of footwear includes securing the peripheral flange to the upper.

A sole structure for an article of footwear having an upper includes an outsole, a plate disposed between the outsole and the upper, and a first cushioning layer. The plate includes an anterior-most point disposed in a forefoot region of the sole structure, a posterior-most point disposed closer to a heel region of the sole structure than the anterior-most point, and a concave portion extending between the anterior-most point and the posterior-most point. The concave portion includes a constant radius of curvature from the anterior-most point to a metarsophalangeal (MTP) point of the sole structure. The MTP point opposes the MTP joint of a foot during use. The first cushioning layer is disposed between the concave portion and the upper.

A shoe includes a sole with a midsole, and an upper portion joined to the sole. The midsole includes a cut having a linear shape, and a depth from a first height position to a second height position in a thickness direction. The cut is configured such that a part of the cut has no contact point with an other part of the cut, and the cut forms a V shape at the deepest part on a cross section when opposite inner walls of the cut are spaced from each other.

A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation assemblies disposed in the shoe sole. A force mitigation assembly adapted for an athletic shoe includes a linkage to a wearer interface responsive to movement based on activity of the wearer. An attachment to a sole surface receives ground forces transmitted from frictional contact between the sole surface and a surface against which the sole is disposed, such as for running, turning, etc. A force mitigation assembly absorbs these forces received from the sole surface for directing the received force in a controlled manner. An elastic field in the force mitigation assembly is defined by a resilient material adapted to deform in response to the received force.

The present invention relates to a pad for strengthening the muscle of the sole of the foot, and an insole including same. The subject matter of the present invention is a pad for strengthening the muscle of the sole of the foot, and an insole including same, the pad comprising: an arch support part for supporting the arch portion; a forefoot support part formed at the front of the arch support part to support the forefoot portion; and a connecting passage part for connecting the arch support part and the forefoot support part, wherein weight moves to the forefoot portion through the outer side of the sole of the foot after a load is applied to the rearfoot portion during walking, and the metatarsal bones come into contact with the forefoot support part and are stimulated so that driving power is generated in the direction between the big toe and the second toe, and thus walking is corrected.

A sole for a shoe includes a sole body extending longitudinally from a heel portion to a toe portion and a curved plate provided at the sole body and extending longitudinally along the sole body. A compressive rigidity of the sole body is lowest at a metatarsophalangeal joint position. The sole body includes a sole forefoot top part disposed above the curved plate at the forefoot portion and a sole forefoot bottom part disposed below the curved plate at the forefoot portion. The compressive rigidity of the sole body is relatively low at the sole forefoot bottom part.
