BOOST™
BOOST is adidas’ most innovative cushioning technology using a material called thermoplastic polyurethane (TPU) that compresses under pressure for better shock absorption and instantly bounces back to its original shape. BOOST foam is believed to offer the highest energy return of any running shoe on the market – thus delivering a more consistent run.
