If you’re a cyclist who measures your performance in hours on the bike, then this is exactly your sort of road bike shoe: rigid and powerful but also comfortable and light. In fact, Mavic designed everything about the Ksyrium Ultimate II Shoes with endurance rides in mind. The entire range features their Endofit tongue, which surrounds the foot giving you what they call The Glove Effect. This "glove" also means the tongue can’t move around in the shoe so it won’t slide sideways during a ride. Endurance specialists will also appreciate the carbon outsoles for great power transfer. The combination of Ergo Dial and Ergo Strap fittings are quick and easy to adjust on the move. And Mavic's Ergo Fit 3D+ Ortholite inner soles will keep your feet supported as your ride time goes from minutes to hours. Or days.
