A sole structure for an article of footwear comprises a midsole coupled to an outsole. The midsole comprises a plurality of sipes on a first side and a plurality of sipes on a second side opposite the first side. The sipes partition portions of the midsole body into impact attenuation cells on the first and second sides of the midsole. The second side of the midsole further comprises a plurality of grooves and a plurality of protruding members separated by the grooves. The protruding members extend from a midsole body towards the outsole when the midsole is coupled to the outsole, spacing the midsole body apart from the outsole. When coupled together, the midsole and the outsole form voids at the grooves. The grooves, protruding members, and sipes provide increased flexibility to the midsole even when the midsole is coupled to the outsole.

A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the direction orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures. An outer covering can be mated with an outsole structure formed by the auxetic structure. The outer covering includes features that mate with the apertures in the outsole structure. The outer covering is elastic and can stretch to accommodate expansion of the auxetic structure.

An article of footwear has a sole member with an exposed central torsion bar or rod connecting the heel region of the sole member to the forefoot region of the sole member. The torsion bar or rod may be supported at either end by sockets of the sole member. The torsion bar or rod may also be supported at one or more intermediate points by a hollow component. This hollow component may itself be supported by ribs extending to the medial and lateral sides of the sole member, respectively. The torsion bar or rod, the sockets, the hollow component and the ribs form a suspension structure connecting the forefoot region of the sole member to the heel region of the sole member.

Methods for manufacturing at least a portion of an upper for an article of footwear that include thermo-forming a pattern on the upper. The methods may include disposing a skin for forming an upper over and inflatable bladder and disposing a mold insert between the skin and a surface of a mold cavity. The mold insert may include a mold pattern including surface features formed in the mold insert. The inflatable bladder may be inflated such that the skin is pressed against the mold insert within a heated mold cavity to form a pattern on an exterior surface of the skin and cause the skin to take on the shape of at least a portion of an upper. In some embodiments, the surface features may be disposed in a gradient pattern configured to provide varying degrees of one or more characteristics to different areas of an upper.

A sole structure for an article of footwear comprises a midsole body having a proximal surface and a distal surface. Proprioceptive elements may extend in the hole in the midsole body, and translate toward the proximal surface in the holes upon a force directed along a central axis of the hole at a distal end of the proprioceptive elements. In various embodiments, the holes may angle relative to vertical from the proximal surface to the distal surface, the holes may be defined by perforations and the proprioceptive elements may be integral portions of the midsole body, or the midsole body may have a plurality of annular holes at the proximal surface, and a plurality of annular recesses in the distal surface, and a plurality of proprioceptive elements, each centered in a different annular hole of the plurality of annular holes. Methods of manufacturing articles of footwear are described.

A method of manufacturing an article of footwear includes forming a midsole body such that the midsole body has annular holes in a proximal surface of the midsole body, annular recesses in a distal surface of the midsole body, and a plurality of proprioceptive elements. Each annular recess encircles a respective different one of the annular holes from below and extends beyond a lowest extent of the respective different one of the annular holes toward the proximal surface. Each proprioceptive element is centered in a different one of the annular holes.

An article of footwear including a sole including a lateral support member, a medial support member and a front support member that are independent from each other and form a triangular contact region on a bottom surface of the sole.

A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the direction orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures. An outer covering can be mated with an outsole structure formed by the auxetic structure. The outer covering includes features that mate with the apertures in the outsole structure. The outer covering is elastic and can stretch to accommodate expansion of the auxetic structure.

A sole structure for an article of footwear comprises a midsole body having a proximal surface and a distal surface. The sole structure includes an outsole having a proximal surface and a distal surface, wherein the proximal surface of the outsole is secured to the distal surface of the midsole body. The outsole includes external flex grooves at the distal surface of the outsole, and the midsole body includes internal flex grooves at the proximal surface of the midsole body. The internal flex grooves overlie and are aligned with the external flex grooves such that the sole structure articulates at the external flex grooves both in dorsiflexion and in plantarflexion.

Golf shoes with a shift structure for shifting the center of gravity of a golfer include two shoe soles. Each shoe sole has a first raised portion at a right side thereof. When the golfer wears the golf shoes, the first raised portion facilitates the center of gravity of the golfer to be eccentric in the target direction. When the golfer swings the club, the center of gravity of the golfer is shifted from the right foot to the outside of the left heel of the left foot, and the front of the golfer's body is turned in the target direction to swing his/her hands simultaneously so as to hit the golf ball correctly. The golfer can swing the club with a shift of his/her center of gravity to make the stroke more strong and effortless and reduce the risk of injury.
