Abstract
A full shoe inlay for athletic shoes constructed of resilient material having a depression for the 1st metatarsal head, a raised portion for the 2nd, 3rd, and 4th metatarsal heads, a full arch support, and an eccentric heel seat. The heel seat is built up more on the inside than on the outside. The inlay prevents or lessens a number of common athletic-related injuries.
