Speed and support go hand in hand in the adidas Supernova ST. By combining the ultra-responsive energy return of boost cushioning with zoned construction and an energy rail, the Supernova ST running shoe helps guide your stride for a more efficient run. With a more efficient stride, you'll be leaps and bounds ahead of the competition and well on your way to a new PR. Breathable engineered mesh upper for a lightweight, yet supportive fit. Zoned boost midsole uses different densities of boost particles to provide areas of responsive cushioning and support where you need them most, encouraging a more efficient running stride. Asymmetrical energy rail helps guide your foot for a smooth, more natural transition from heelstrike to toe-off. Continental rubber outsole with Stretchweb construction delivers durable traction on any surface while allowing the boost midsole to expand with the natural motion of your stride.
