When you're giving it your all on tight, twisty singletrack, you want a shoe that can keep up with you. Enter Giro's Gauge HV. These great mountain-biking shoes offer stiffness and lightness from Giro's Easton flat carbon soles that provide the perfect perch for your feet and a nearly direct connection to your pedals for maximum efficiency. The great fit is courtesy of the breathable microfiber uppers and Giro's included ergonomic and antimicrobial footbeds. Plus, the double hook-and-loop straps and ratcheting-buckle straps vary in width to provide the ultimate fit and feel. You also get padded heels and split tongues for additional comfort, plus aggressive treads for maximum walking traction.
