Built with high levels of power transfer and comfort in mind, the Lake CX217 Men's Shoes give you many of the desirable traits of Lake's flagship CX402, but without its uncompromising commitment to race performance. Its action leather and mesh upper provide a well bolstered feel, with ample ventilation for warm weather comfort. The Boa closure dials in a precise fit with the flick of a reel, removing any slop from the shoe when you're pedaling furiously up steep climbs and attacking sprints. The CX217's Competition last strikes an ideal balance between power transfer and comfort, giving the foot a bit more space to expand along the forefoot region. However, it still places the foot in an ideal position to transfer power to the pedal, making it a great choice for the endurance racer and long distance rider. And speaking of power transfer, the Lake Race outsole is made of 100% carbon fiber to ensure every gram of energy is transferred into forward momentum.
