This pair of running shoes from Adidas has a rubber outsole with a superior grip that adapts to footstrike by moving in harmony with boost. The Adidas Linear Energy Push increases midfoot and forefoot stiffness reducing the amount of energy exerted in every step. Boost is the temperature-independent cushioning that provides energy return in all climates. The textile upper flexes with your foot for breathability. A full-length Boost midsole gives responsiveness and energy return. The Stretchweb outsole flexes for an energized ride. An external heel counter locks down the foot for a secure fit.
