Pearl Izumi X Road Fuel III Shoes. The Pearl Izumi X Road Fuel III shoes may look like a regular pair of running shoes, but once on the bike you'll quickly discover they're performance cycling shoes, too. The X Road nylon plate in the sole ensures fantastic pedaling efficiency while the shoe's 2 bolt SPD pedal compatibility means you can take full advantage of clipless mountain bike pedals. The low cut construction and running shoe aesthetic, however, give these shoes a versatility lacking in most cycling footwear. The flexible forefoot and beveled heel serve up running shoe comfort, a rubber lugged outsole gives you a dependable traction, and a built in lace garage means nothing will get snagged in your bike's drivetrain. Equally at home in the woods, at a spin class, or just heading out for errands or a stroll, there's plenty to love about these shoes.
