The Lake CX239 Road Cycling Shoes are made to give unrivalled cycling performance, with a supple upper and carbon sole unit delivering the perfect balance of comfort and instant acceleration. Technology trickles down from the CX333, including the easy-to-adjust BOA Li2 dial system and the integrated tongue, giving an easily customisable fit and reassuringly secure foothold. The Outlast tongue and heel lining keep your feet feeling fresh while an internal heel counter locks in your foot for a powerful and supportive pedalling platform.

The 80K Force carbon sole makes for eye-watering acceleration and super-efficient power application. Rated 80/100 on the Lake Force Resistance Scale, it's just right for rapid accelerations out of corners, powering up climbs and sprints for the finish.

The CX239s use Lake's CX/TX Competition Last. This gives the shoes a snug race-oriented fit with a curved profile, increased toe pitch and extra heel lift for an aggressive riding position. It also provides a slightly wider ball girth, allowing the foot to expand naturally under high pedalling pressures, while the tighter heel ensures a locked-in feel, delivering both comfort and control on the bike.

Sizing note:

Lake shoes run small. We recommend sizing up — most customers find they need one full size larger than their usual EU size. If you're between sizes, always go up. This applies to both the standard and wide fit versions.
