Rugged sole meets athletic spirit. The Gauge mountain bike shoes feature a lugged rubber outsole for traction with a stout injected-nylon inner shank to help transfer your power, so you can tame the trail. It combines cycling-specific features like clipless pedal compatibility and supportive fit, with the reliable grip of an aggressively lugged rubber outsole and the feel of a trail running shoe. With an upper made from supple synthetic fiber and breathable mesh, and a stout injected-nylon inner shank to help transfer your power to the pedals, it&';s a capable cycling shoe that gives you the confidence to take on any trail. Synchwire construction is a stitchless upper that&';s vented and reinforced to create a lightweight cycling shoe with incredible airflow and structural integrity. Synchwire is an advanced composite of thermobonded film that provides overall durability, a nonwoven internal sheet for distributing the force from the closure system to the upper for direct power transfer, and monofilament mesh for ventilation. Rock Print reinforcement along the toe and heel offers abrasion resistance and enhanced durability. In addition to infinite adjustability and the capability to conform to each zone of the foot, laces offer easy replacement and customization, a more natural feel across the foot, and reliability in even the most adverse conditions. Our tubular woven laces are designed to be highly durable, light, and to hold a knot securely without slipping.
