Abstract
Abstract A multilayer material includes a first layer of polyether foam or polyurethane foam, a second layer of a woven or knitted material adherent to a first surface of the first layer, and a third layer of a reprocessed foam material, consisting of flakes of polyether, polyurethane or both within a polyether linking agents or a polyurethane linking agent, adherent to the second surface of the first layer.
