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, Energy Boost and NMD lines of sneakers. The pellets consist of proprietary thermoplastic urethane (TPU) that is formed 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.[1][2][3][4]

History

Prior to its first integration into the Adidas running line in 2013, this technology was developed by chemists at BASF, BASF sold its product to Adidas and Adidas Innovation Team (AIT) used BASF's new foam and engineered it into the midsoles we see today, that has made a name for itself and is now known as BOOST technology. This was an improvement upon what was then the industry standard for sneaker midsoles: ethylene vinyl-acetate, or EVA for short. Adidas saw that EVA was contradictory in its promise for softness and responsiveness in terms of cushioning ability, and therefore sought out to create Boost specifically for delivering comfort and energy return in the same package.[5]
