A footwear sole structure may include a plurality of discrete hexagonally-shaped sole elements defined by a plurality of sipes. The sipes may include a plurality of sipes that extend in a transverse direction across the sole structure and a plurality of sipes that extend in an oblique direction relative to the transverse sipes. A plurality of sipes may also subdivide the hexagonally-shaped sole elements into one or more diamond-shaped sole element portions. The sole structure may include additional features such as non-hexagonal sole elements and lugs distributed across a bottom surface of the sole structure.

The present invention relates to a shank adapted for being integrated into a shoe sole and for mounting a heel element, wherein said shank at its heel portion is adapted to be connected to the heel element and wherein said shank comprises an upper surface pointing towards the inner shoe. At least a part of the upper surface at the heel portion is cup-shaped and adapted for receiving sole material inside the cup when integrating said shank in said sole during moulding of said shoe sole. Thereby, due to the amount of sole material present in the heel portion, the sole material covers the means used for connecting the shank to the heel element. Thereby, based on the properties of the sole material, the heeled shoe becomes comfortable and flexible at the heel portion. The invention further relates to a sole for a shoe with a cup-shaped shank and more specifically to a shoe with a cup-shaped shank.

An article of footwear includes an upper defining a forefoot region, a midfoot region, and a heel region of the article of footwear. The article of footwear further includes a sole structure coupled with the upper, the sole structure comprising a midsole defining a v-shaped notch; an outsole coupled with a bottom surface of the midsole, and a plate that is disposed between the midsole and the upper. The plate is coupled with the midsole in the forefoot region and the heel region, and a gap is formed between the plate and the midsole in the midfoot region, and at least one sole aperture is disposed within the sole structure.

A spine for an article of footwear includes a base extending from a first end to a second end. The spine also includes a sidewall extending transversely from the base from the first end to the second end. The sidewall has a plurality of sidewall supports including a forefoot sidewall support at the first end, a heel sidewall support at the second end, and a mid-foot sidewall support disposed between the first end and the second end and defining a maximum height of the sidewall.

A method for manufacturing a sole of an article of footwear uses an additive manufacturing through a 3D printer. The sole body 20 has an inclined surface or a curved surface BL.sub.0 to be a supported surface by a support at a toe spring portion Tu/a heel-up portion Hu/a side-up portion Su. The method includes a forming process in which a plurality of pillar-shaped supports 20sp that extend from the inclined/curved surface BL.sub.0 toward the bottom surface of the sole at the time of forming the sole through the 3D printer, and a cutting process to cut at least a portion of the pillar-shaped supports 20sp.

A system and method for footwear with a handless entry construction. A heel band may be provided in the footwear that is sufficiently deformable and sufficiently resilient to handlessly a) facilitate insertion of a wearer's foot into the footwear and b) move upward relative to a ground surface to engage a heel of the wearer's foot in order to aid in securing the wearer's foot within the footwear.
