Shimano M163 Mountain Shoes. If aggressive trail riding or enduro action is your cup of tea then the Shimano M163 Mountain Shoes belong on your feet. Providing superb traction off the bike, they're also plenty stiff enough to deliver excellent power transfer when you're flying along your favorite trail. The M163 features a tough synthetic leather upper beefed up with low profile armor for exemplary foot protection and durability. Torbal technology provides a better connection to the pedal and allows lateral movement for improved control. Single density, extra cushion insole offers stability and shock absorption while the volume last gives you more room in the toe box. A precision fit is ensured via the micro adjust ratcheting buckle coupled with a pair offset Velcro straps. And all those watts you generate go straight to the pedals thanks to the fiberglass composite midsole.
