If you’re looking for one package that offers superb stiffness and minimal weight, the SCOTT Road RC EVO is your shoe of choice. Primed for attack, it features a seamless, ultra comfortable laminated TPU & airmesh upper. The dual-zone Boa® Fit System with IP-1 dials allows on-the-fly adjustability at the ankle and at the forefoot. For optimal foot support, the ErgoLogic insole features an adjustable arch support and metatarsal button. The stiff HMX Carbon fiber sole has a stiffness index of 10 (our stiffest, for pure efficiency).
