The F35KN features a redesigned F35 knit with a seamless upper with TPU protection to ensure maximum foot strength in the shoe. The knit also enhances comfort and the new tighter fit aids in a sleeker design. The manufacturers have relied on reinforced leather heel support instead of mesh, and added a few extra vents to the upper for better ventilation. A triple layer of nylon makes sure that the upper doesn't stretch and fits securely to the foot. The lacing has remained the same as the F35 - three Velcro straps, or you can choose a new lace option this time. The R250 road sole remains lightweight and provides the perfect combination of stiffness and compliance.Weight 257 g
