Abstract

A composite sole structure for footwear and the like is disclosed. The sole structure includes a plurality of adjacent tubular members adapted to contain a gaseous medium under pressure at a selected value. The tubular members are provided with a composite structure including an inner layer of resilient elastomeric material impermeable to diffusion of the gaseous medium therethrough; an outer layer of a flexible mesh material resistant to expansion but sufficiently compliant to cooperate with the inner resilient layer to provide a cushioning effect in response to shock forces and a resilient flexible material forming a matrix about the tubular members. In an alternate embodiment aa second or outer layer of a resilient elastomeric material is provided over the flexible mesh layer to provide additional strength and resistance to diffusion of gases. The tubular members can be varied in length, size, and configuration and can be constructed and arranged to run lengthwise (toe to heel), transversely, and diagonally thereof and in a serpentine-like configuration within the sole matrix.
