CONTOURED INSOLES FOR FOOTWEAR

摘要

An insole assembly for use in footwear is provided. The insole assembly generally includes a full-length insole base made of a flexible and resilient material (e.g., resiliently compressible foam), and a heel cap made of a generally rigid material (e.g., a carbon fiber reinforced polymer) which is attached to the insole base and mimics the contours thereof to provide proper biomechanical support of the heel and arch areas of a foot in a particularly lightweight and sleek form factor.

主权项

1. An insole assembly to be inserted in an item of footwear to provide foot support, the insole assembly comprising:
a flexible full-length insole base having an upper contoured surface for engaging a plantar surface of a foot and a lower contoured surface opposite the upper contoured surface, and including a heel portion, a forefoot portion and midfoot portion between the heel portion and the forefoot portion; and a rigid heel cap having an upper contoured surface and a lower contoured surface opposite the upper contoured surface which has the same general contours as the upper contoured surface to define a thin shell structure, the rigid heel cap being bonded to the flexible full-length insole base with the upper contoured surface of the rigid heel cap in contact with the lower contoured surface of the flexible full-length insole base to underlie at least the heel portion thereof and provide support thereto, and the rigid heel cap including a plurality of engagement features protruding from the lower contoured surface thereof to engage a midsole of the item of footwear during use and to resist motion of the insole assembly relative to the midsole.
