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.

Articles of footwear can include an adaptive-height sole structure that includes a variable height bladder system. The sole structure can include one or more bladder systems positioned between a midsole and a banking plate. The banking plate can change its relative orientation to the midsole based on an inflation level of the bladder systems.

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 sole constituting a part of footwear includes a shock-absorbing part provided at least in a rearfoot region, the shock-absorbing part cushioning an impact applied to a heel of a foot upon landing, and a support part provided at least in a midfoot region, the support part being higher in rigidity than the shock-absorbing part and supporting a midfoot portion of the foot, the support part includes a support surface, the support surface being provided forward of the shock-absorbing part and having a shape extending from one end to the other end in a width direction, and the shock-absorbing part includes a recessed surface located at a height position lower than the support surface, and a plurality of columnar bodies each having a shape extending from the recessed surface to a height position identical in height to the support surface.

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 structure for an article of footwear. The sole structure includes at least one support plate located on an underside of a midsole on a medial forefoot side of the midsole and extending from a medial edge of the midsole to at least a longitudinal center line of the midsole, wherein a lateral edge of the plate is located medially of the lateral edge of the midsole. The support plate may contain at least one sipe or groove extending laterally across the midsole to provide flexibility in a forefoot-to-heel direction of the midsole. The support plate may contain at least one rail.

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.

A sole structure for an article of footwear including a forefoot region disposed adjacent an anterior end, a heel region disposed adjacent a posterior end, a bottom cushion extending from the heel region to the forefoot region, a heel cushion coupled to a top surface of the bottom cushion in the heel region, and a support plate coupled to a top surface of the heel cushion in the heel region. The sole structure further includes a top surface of the bottom cushion in the forefoot region and a top cushion coupled to a top surface of the support plate.
