Nike says its Mind Science Department spent several years studying the unconscious side of sport preparation, and it designed this mule for ease, so athletes can slip it on without effort. Here the Nike Mind 001 Pregame Mule comes in 'Solar Red', with Hyper Crimson, Black and Chrome alongside. Underfoot, 22 nodes rise and fall against the foot, and a stretchy fabric over the footbed leaves them space to do so. The knit tongue is perforated to let air through.
