The perfect combination of comfort, foothold and energy transfer, the Mavic Ksyrium Elite II Road Shoes are Mavic's best sellers, thanks to their versatile features and high performance construction. These shoes combine the precise adjustment of the Ergo Ratchet system, the comfort of the Endofit Tongue and the power of the Energy Comp Carbon outsole. Fiberglass/nylon composite platform with low stack height is extremely light and stiff for better energy transfer. Endofit Tongue hugs the foot in just the right places while Ergo Fit 3D+OrthoLite inner sole gives superior cushioning and comfort. Comfort Straps with supple microfiber offer support and Ergo Ratchet locks the foot in place and allows 2mm adjustment increments for an exact fit.
