Shimano designed the SH-AM45 Mountain Bike Shoe so you could tackle a trail without the trail tackling you. The AM45 is built with a raised outsole that wraps around tough synthetic leather to offer added protection for rough sections of trail. The mid-top design protects your ankle while the no-mesh design keeps dirt and rocks out. A specially designed ultra-grip outsole stands up to trail debris and keeps you from landing on your butt when you get off your bike, and the fiberglass-reinforced polyamide soleplate transfers power directly from your foot to the pedal. SPD compatibility allows you to clip in for more tolerable pedaling sections.
