Mavic designed the Ksyrium Men's Ultimate II Shoes with long mile cyclists in mind. The Ksyrium Ultimate is built with a comfortable upper and a stiff, full carbon sole to efficiently weather gran fondos, epic double centuries in the high mountains, and any other endurance road excursion you might imagine. Mavic incorporates perforations and strategic mesh paneling in the Ksyrium Ultimate's upper, which offers some much appreciated ventilation and breathability to keep feet cool through long summer rides. An Endofit tongue provides a comfortable, glove like fit while evenly distributing pressure across the top of your foot. An Ergo Dial Boa strap wraps across the top of the foot, while two Ergo hook and loop straps span the midfoot and forefoot to dial in a customized fit that's easily adjustable on the fly.
