The Leatt ProClip 6. 0 Endurance MTB shoe is built for everyday XC and gravel rides, with an injected nylon shank that keeps the sole flexible. RideGrip rubber with an aggressive tread backs it up when a ride turns into a walk. What Our Gearhead® Experts Are Saying:“I leave the lacing a little loose on easy climbs, and the heel fabric still keeps my foot from lifting out the back. When I hop off to walk and hop back on, I don't have to stop and retighten anything.”
