Boost (material)
Boost is a trademarked polymer used by Adidas, in the form of pellets which are compressed and molded for various shoe models the company sells, especially the Ultraboost and NMD lines of sneakers. The pellets consist of proprietary thermoplastic urethane that is extruded and/or molded into a small pill shape. Adidas collaborated with the German chemical company BASF to develop this material. Boost in itself is not a raw material and its characteristic bounciness is obtained by processing the thermoplastic urethane. This material is claimed to be extremely comfortable on the wearer's feet.
