The body of the F-35.III rests on the lightweight R250 outsole to provide the perfect blend of stiffness and comfort. The shoe is secured by new low-profile straps. The main, hook-and-loop strap is angled to provide effective heel support while helping to resuce friction and an easy opening. The middle D-ring over strap provides a customisable adjustment to the shoe's volume. The smaller strap near the toes fastens to the outside of the foot per usual; it secures and warps the forefoot and allows you to dial in for the perfect fit.
