ABSTRACT:
An insole construction for an athletic shoe has a shell portion that is positioned under the heel and midfoot of the foot, and is covered with an insole and having low friction material on the upper sides in selected regions. The low friction material may be a thin layer of polytetrafluoroethylene material, the low friction material extends across the heel region, and/or across the metatarsal area, and these areas may be joined by a lateral side strip. The shell is cupped to form a wall along the lateral side of the foot and about three quarters of the way behind the heel or calcaneus region of the foot. This cup wall is joined to a base wall with a generously radiused rounded portion that mirrors the concave/convex contour anatomy of the foot in this region for comfort and for distributing impact forces received during running, across a substantially increased contact area of the foot.
