Add an edge to your game with the new AlphaEdge 4D. Designed for peak performance during your cross-training workouts, this model features a 3D-printed midsole. The lattice structure was developed using years of athlete data to deliver precisely-tuned support and cushioning right where you need it. The process is called digital light synthesis - light creates the shape of the sole, heat sets it. This model features iridescent panels inspired by the galaxy. Our formula for the future.
