Lace-up for some flat-pedal fun with the Shimano GR5 Mountain Bike Shoe. Featuring proprietary Shimano rubber on the sole, the platform shoe grips with ease and also makes walking and bike hiking more enjoyable than with clip-style cycling shoes. The breathable synthetic upper manages moisture to keep your foot from feeling swampy, and the reinforced toe and ankle zones take any trail hits for you so you can shred more confidently. And the GR5 uses Shimano's Volume Last to give room for comfort all day on the trails.
