The high-energy and high-speed demands of cross-country racing require purpose-built equipment that carries no extra fluff, and the low-profile, single Boa design of the Shimano XC3 Wide Mountain Bike Shoe is the tool of the trade. Starting with an integrated upper and midsole that sees synthetic leather wrapping around your feet with superior fit and comfort, the XC3 sets a no-frills image of performance-first design. The stand-alone Boa L6 dial cinches down the upper to precision comfort on your trail riding or race-pace interval sessions. With a low stack height, the XC3 reduces energy loss while pedaling, and the fiberglass-reinforced nylon sole transfers watts into the pedals to keep you in the hunt for the win. And rubber tread grips well should you need to put a foot down, sending it deep into a tight apex. This wide last version provides more room in the last for greater comfort and better overall fit for some riders.
