Performance doesn't always come at a crazy price and the CX177 cycling shoe proves it. They are made for cyclists those who prefer extra-hard soles without compromising on comfort. Fiberglass injected nylon outsole provides essential rigidity and power transfer while the Clarino microfiber and mesh upper is lightweight and provides a comfortable fit. L6 Boa side closure system allows us to find the perfect fit making slight micro-adjustments if necessary. Carbitex tongue inserts reduce friction , providing smoother and easier tightening of laces and the Lake Sport last holds the foot in place, preventing unnecessary movement.
