Bont's Riot TR Shoes are heat-moldable for a custom-fit and built to withstand the rigors of triathlons. Stiff resin—that is easily moldable at relatively low temperatures—lets you use a conventional oven to fine-tune the snug fit. Your arches, heels, and forefeet are all supported to ensure a neutral position that protects your knees. The main Velcro straps are notched to stay open for quick transition times. Plus, mesh panels and vents along the microfiber side panels keep your feet dry once you’re out of the water.
