Lake evolves the CX237 to the new CX238 with updates to improve the longevity and performance of this long-time favorite road racing shoe. The Competition last is shaped for better fit and comfort during hard efforts, with a slimmer heel and wider forefoot to allow for foot expansion under pressure. Supporting it all is Lake’s Race carbon fiber sole, providing the stiffness we need for better power transfer and durability. A panel at the heel and a rubber bumper at the toe protect from prematurely wearing out the full-grain leather upper, which has mesh panels and venting to improve cooling.
