The CX403 is the pinnacle of cycling shoes. Every aspect of this shoe is purposeful, with a goal of offering the highest performance and comfort while also delivering optimal power transfer.
CX/TX RACE Last:
Featuring a slightly more narrow toe box and tighter heel than the Competition last and less overall volume than the Sport last. Designed for very high-cadence riding with a slimmer fit.
Outsole:
Custom Fit Carbon Fiber sole with a replaceable heel strike pad. Available in a 3-hole cleat pattern.
Upper:
Klite Kangaroo leather & Carbitex OmniFlex Carbon Fiber Stabilizer Support panels help keep the foot stabilized, control stretch and allow for increased power transfer. Lined with Perforated Kangaroo leather for great fit & feel. Moldable carbon heel.
Closure:
BOA® Fit System. The BOA® dial is the most advanced platform in cycling, offering a precise, micro-adjustable fit in both directions and designed to resist abrasion.
Fit:
The CX403 uses a unique monocoque carbon construction shared only with the CX400 and CX400L. The upper wraps around an integrated carbon outsole and heel counter, creating additional fixed internal volume compared to traditional Race Last models where the sole is bonded beneath the upper. Because of this construction, the CX403 may feel slightly roomier than models such as the CX333 in the same size and width. The added volume comes from the carbon shell rather than the last shape itself. Despite this additional space, the integrated carbon heel and sole structure create exceptional rearfoot stability and one of the stiffest, most supportive performance experiences in the collection. Riders coming from softer uppers may notice a more structured feel across the heel and arch. If you are between sizes or prefer additional room, consider sizing up 0.5–1 size. You'll find a detailed size chart in the pictures.
