The Scott Road Tri Carbon cycling shoes are designed for triathletes like Sebastian Kienle to maximise their race performance. By placing the BOA® IP-1 closure system on the heel, we were able to create a much smoother and cleaner shape. The design thus saves valuable watts without detracting from stiffness or comfort. The HMF carbon sole with a stiffness index of 9 will ensure zero-loss power transfer to the pedals.
