Riccardo Tisci is back with another collaboration for NikeLab and this time the designer takes his aesthetic to their gym wear with the Free Train Force Flyknit. The blacked-out sneaker features a Flyknit upper to give you that supportive, sock-like fit, a dual-density midsole that is ideal for everything from cardio to crossfit, and a flexible Free outsole moves with the natural motion of your foot. The shoe hits NikeLab's online store and select retailers tomorrow.
