Reinforced sole and heel for footwear has slender reinforcing elements extending to at least half thickness of flexible sole material in which they are embedded

摘要

The footwear sole and heel consists of a layer (11) of a flexible material such as a compact or cellular elastomer containing reinforcing elements (8, 15) that are slender in shape, i.e. with crosssections inferior to their length, and extend to a height equivalent to at least half the thickness of the sole. The reinforcing elements, which are made from an optionally reinforced or expanded elastomer material and enlarged at the base (7, 16), are embedded in the flexible material of the sole and are angled at 30 - 150 degrees to its outer surface. They are also shaped to promote deformation by flexion. An independent claim is included for a manufacturing method of the inventive shoe soles comprising attaching the reinforcing material to the sole.
