Abstract
A treadmill belt is provided having a base layer of synthetic fabric over which a stabilizing layer of polyvinylchloride is deposited. The combined base layer and stabilizing layer are formed into a continuous belt over which a compressible cushion layer is deposited. The opposing ends of the cushion layer are stitched together at a select angle relative to a transverse axis extending across the treadmill belt.
