Details: Designed with performance in mind, the adidas Alphabounce EM was created using motion capture technology to determine which areas of the foot are irritated or restricted while running. Focusing on eliminating these distractions resulted in an ultra-sleek silhouette that looks as good as it performs. The Alphabounce’s sock-like upper stretches and moves with the foot, working together with the full-length Bounce midsole to create a fluid running experience from heelstrike to toe-off. Bounce is also comfortable enough for all-day wear, so you can rock the Alphabounce anywhere and everywhere. Engineered mesh upper adds comfort and style, with a soft, sock-like fit and premium texture that's sure to turn heads. Full-length BOUNCE™ foam midsole delivers comfortable cushioning with every step, keeping feet fresh over your long-distance run or through all-day wear. adiWEAR™ rubber outsole for durable traction on any surface.
