Lake CX333 Narrow Road Cycling Shoes Introducing Lakes new CX333 Narrow road cycling shoes, the latest evolution of the classic CX332, enhanced with several updates and improvements. Now equipped with the Carbitex arch support panel, ensuring a more secure fit. The narrow modle features a slightly narrower toe box and tighter heel than the Competition last and less overall volume than the Sport last. Designed for high-cadence riding with a slimmer fit. The CX333 uses Lake’s patent double sole system. This features an inner sole made from semi flexible fiberglass platform allowing some flexibility at the ball of the foot where the foot tends to swell and typically hot spots or numbness would occur. This inner sole is suspended over an outer rigid carbon sole. This system enables Lake to use an extremely stiff carbon outsole without sacrificing riding comfort. Choose between Klite Kangaroo leather and leather lining or a Microfiber upper with Outlast temperature-regulating lining & Carbitex Medial Support panel for added security. The Internal Thermaform Carbon Fiber heel counter is heat-moldable carbon, allowing for a personalized heel hold. This secure hold stabilizes the foot, reducing heel slip, enhancing power transfer, to minimizie fatigue. The form-fitting Natural leather upper, combined with the dual BOA® closure system, guarantees a secure fit without the need for excessive tightening.
