The two tone knitted upper of the Ignite is designed in such a way that the shoe looks 4-dimensional. The racing stripe pattern creates an illusion of movement, of speed, and adds an allure to the wearer. That’s not all there is to it. The Ignite also has dual technology – Flexiknit in the upper, and Ultrahop in the insole. Flexiknit in the uppers makes them snug and seamless, and provides 4-way flexibility so that the foot is supported in every movement. Ultrahop inoles have reflexive cushioning – this means the insole provides constant, responsive cushioning no matter what the movement!
