Footwear, Shoes and Boots Design Y3 Neue Treadmill Running Shoe by Refaeli Yaofei Ma The Y-3 Neue breaks with tradition in both form and function. Equipped with advanced Equal gel and artificial ligaments, bring comfort while meeting your athleisure aesthetic needs. Y-3 Neue helps runner interacts with the shoes better than ever. A carbon fiber piece cooperates with the artificial ligament starting from the bottom lateral side, going up across the insteps then separating into two directions. The two pieces work together to hold the runner's heel properly and prevent the abnormal ankle twist during the running.
