Constructed with a carbon composite outsole and breathable upper that's bonded and welded for lightweight comfort, the Giro Sentrie Techlace Road Shoes provide elite-level fit and performance and allow multiple adjustments. Patent-pending Techlace system replaces D-rings and other hardware with laces, creating a more supple feel across the forefoot. Plus, the laces can be easily replaced if damaged. BOA Closure System with premium IP1 dial offers 1mm adjustment increments when tightening and easy pull-to-release function for quick in and out of the shoes. Easton EC70 outsole transfers power directly to the pedals, thanks to its rigid platform. SuperNatural Fit Kit with adjustable arch support helps to personalize comfort and fit. There's replaceable walking pads, steel hardware and microfiber/mesh upper for a supple, well-ventilated riding experience.
