Lake MX236 Carbon Mountain Shoes. Good mountain biking shoes can be tough to find...you want the efficiency of carbon, but don't want to feel like Frankenstein when you're off the bike. The Lake MX236 Mountain Bike Shoes have that carbon sole, but are designed to give just the right amount of flex just ahead of the cleat for easier hiking. Full grain leather uppers and mesh work with a vented heel to give you comfort, cooling, and moisture expulsion. A mountain Race X rubber outsole is lugged for great traction, and a heel mounted BOA closure secures the perfect fit for performance and comfort.
