Abstract

A shoe construction utilizing a gas containing chamber as a cushion. The shoe includes a stabilizer positioned in the shoe and having a heel portion in overlying relation to the cushion and a forward portion in overlying relation to at least a midfoot portion of the shoe bottom. The forward portion extends across a substantial portion of the inside width of the shoe where it is located to resist deformation of the shoe bottom under load from a user both in lateral bending and longitudinal torsion.
