The Giro Terradura Women's Mountain Shoes strike the perfect balance between super stiff-soled shoes that transfer all the power but aren't great for walking and soft-soled shoes that walk well but feel squishy on the pedals. Giro uses a strong and durable nylon shank that's stiff enough to get down the trail fast and just flexible enough to keep your heels in your shoes when hiking your bike up a steep incline. A Vibram lugged outsole also grips rocks and other obstacles that you come across on the trails better than shoes that come outfitted with plastic lugs. Even with all that attention to the outsole, Giro didn't ignore fit. The Terradura's upper is designed to fit a narrower foot, with a ratcheting buckle and two hook-and-look closures for a comfy and secure fit. Perforations in the microfiber upper let feet breathe, and toe box reinforcement provides durable impact protection.
