Shimano GR5 MTB Shoes Using a skate-shoe style design, the Shimano GR5 MTB Shoes are ideal for use with flat pedals whether mountain biking off-road or nipping round town on a hybrid. The sticky rubber sole with smoother central area gives great purchase on the pedals yet still allows for easy adjustment of position when required. When off the bike sections of tread at the heel and toe provide extra traction. Guards around the toes and a higher, padded inner ankle provides protection against knocks and scuffs whilst the tough synthetic leather is also breathable for comfort on warmer rides.
