Running sneakers made from an ultra-lightweight, comfortable fabric. The Nitro Wave style is based on the use of a revolutionary nitrogen technology applied to the midsole, making it extremely light and responsive, allowing the wearer to use less energy when running. The innovative material, made with a foam that blends with nitrogen gas, offers three advantages: responsiveness, shock absorption and lightness. The logo represents the fusion of two elements: the “N” symbol indicating Nitrogen and the number “7” from EA7.
