Abstract
A sole insert for use in footwear includes a toe plate portion, a metatarsal portion and a heel portion all formed in an integral molded member. The heel portion includes a thickened block-type reinforcing frame merging smoothly into a similarly constructed-type metatarsal portion of reduced thickness which in turn merges into the flat toe portion. The toe portion includes laterally extending weakened portion such that the insert will resist to torsional twisting but will flex about a lateral axis located in the toe portion.
