ABSTRACT:
A shoe sole insert has foam-filled independently compressible regions that extend through a midsole and beyond an outsole bottom surface so a particular region, when it strikes a traversed surface, is compressed vertically and expands horizontally against the midsole. In one embodiment, five groups of such regions are beneath the metatarsal bones and proximal phalanges. In a second embodiment, two transversely extending regions are beneath forward and rearward portions of the metatarsals. The rearward transverse region has a ridge that is farther from the outsole bottom face than a ridge of the forward transverse region. In another aspect, an array of regions below the tarsal and calcaneus bones is arranged so a region at the very rear of the heel compresses vertically to a greater extent than a lateral side region in response to the same striking force, so pronation tends to be corrected.
