The Lake MX333 Shoes help cross country, trail, and gravel riders perform at a race-ready level. The upper gives riders a choice between Helcore leather and microfiber, with the blue shoe being the non-leather option. Note that Microfiber uppers will fit tighter and have limited stretch. Both are lightweight, water resistant, and extremely durable. A special temperature management lining is in the shoe as well to avoid overheating. The sole is made of 100% carbon fiber and is geared toward riders who spend most of their time in the pedaling position. This provides maximum power transfer and the fastest ride. The sole also accepts toe spikes for the ultimate traction. The internal moldable heel is also made with carbon for excellent stabilization and stiffness. A dual Boa system allows you to precisely dial in your fit. The Lake MX333 Shoes offer the highest level of MTB and gravel performance.
