Whether you're looking to shave watts wherever possible or have an affinity for the smooth, pared down road shoes that have come into style as of late, Mavic's CXR Ultimate II Shoe is worth consideration. As its headlining road shoe, the CXR Ultimate II was held to Mavic's loftiest footwear standards, receiving lightweight, flexible materials and a design that shaved every unnecessary gram and piece of material to deliver the lightest, most responsive shoe possible.

To address biomechanical efficiency within the shoe, Mavic also includes its Ergo Fit 3D inserts, which are designed to be paired with the OrthoLite foam insoles that line the inside of the C...
