Shimano TR70 SPD-SL Triathlon Shoes: The benchmark in high performance Triathlon shoes for the ultimate in performance, with a Hollow carbon sole and Custom-Fit technology. The TR70 features custom-Fit material in the upper, moulded to conform to the contours of your feet for precision fitment and the ultimate in comfort. The toe box is moulded for support and protection. The Custom-Fit vented insoles have an anti-bacterial treatment and raised arches that can be moulded to the foot giving the perfect fit. The Hollow Nano carbon fibre sole keeps the shoe rigid and the weight to a minimum to meet the demands of Triathletes. Nano technology strengthens the layers of the carbon weave producing a rigid and lightweight sole. A Soft and seamless lining allows use without socks without chafing, and is quick drying. A Wide reverse-closure 45 mm main hook-and-loop strap offers rapid fitting, adjustment and support on the go, with an added strap for increased stability across lower part of the shoe. Rubber protection on the heel prevents damage to the shoes in the transition.
