The innovative BOA closure system, combined with a supple full-grain leather/ mesh upper, creates a 'pressure free' cycling shoe that conforms to the shape of your foot. Lake likes to call the CX236C an "invisible shoe" - a shoe that does not cause hotspots! The unique BOA lacing system uses strong nylon strands to cinch the uppers together via a ratcheting Micro-adjust dial in the heel, drawing the uppers down and back for a secure, non-bulky fit. A lightweight carbon fiber sole ensures excellent power transfer. Standard 3-hole cleat pattern.
