摘要:
A midsole for footwear comprising a midsole element, which comprises a top plate, a bottom plate, and a plurality of strut members disposed between the top and bottom plates for supporting the top plate a distance away from the bottom plate. Adjacent strut members have a C shaped cross-section facing in the same direction. The midsole element may further comprise a heel cleft to increase the flexibility of the sole. In a preferred embodiment, the strut members on the medial side are arranged at an angle to the strut members on the lateral side of the sole. The directional design provides flexibility and stiffness anisotropically to the sole in the longitudinal and lateral directions of the sole respectively.

The invention relates to parts having a foamed polymeric material attached to a fabric, and systems and methods for forming same. An example method of attaching foamed polymeric material to a fabric layer includes providing a moid having at least one cavity and at least one material injection channel in fluid communication with the cavity., disposing a fabric over the at least one cavity, closing the mold, injecting unfoamed polymeric material into the at least one cavity through the material injection channel, wherein the unfoamed polymeric material penetrates at least a portion of the fabric proximate the at least one cavity to attach the polymeric material to the fabric layer, and foaming the unfoamed polymeric material.

A shoe sole and shoe are provided for offsetting a wearer's side-to-side balance to encourage a wearer's conditioning and toning. The shoe sole includes a midsole width that underlies and supports a wearer's foot, and an upper midsole portion undercut at its peripheral sidewall around the heel to define a horizontal indentation. A lower midsole portion has a corresponding "undercut" in its upper surface that angles downward and outward from the indentation. The depth of the indentation forms a balancing portion between the medially and laterally placed indentations that is narrower than the midsole width, thereby forcing the wearer to adjust one's walking gait to maintain balance over the balancing portion. A structure with a base portion can be disposed along the indentation with upward and or downward extending extensions disposed along the peripheral sidewall. The structure can include leaf springs extending transversely over a central midsole portion.

The invention relates to systems and methods for creating a foamed part. An example method includes providing a polymer processing system, providing a mold having at least one expandable mold cavity in fluid communication with the polymer processing system, mixing polymeric material and blowing agent within the polymer processing system to produce a unfoamed mixture, injecting a volume of the mixture of polymeric material and blowing agent from the polymer processing system and into the expandable mold cavity, and expanding the mold cavity to expand the unfoamed mixture within the mold cavity and form the foamed part.
摘要:
An insert for footwear which has improved durability and pliability and satisfies a thumb test of pliability when exposed along the sides of the footwear. The insert comprises a compressible core at least partially surrounded by a flexible casing. The flexible casing has an open window of a size which is sufficient for insertion of the compressible core into the flexible casing but leaving sufficient material to hold the compressible core. The peripheral portion of the flexible casing is spaced from at least a portion of the peripheral surface of the compressible core, while not interfering with the foot applying pressure to the compressible core. A method for making the insert is also provided.
