Lake CX403 Shoes - Wide Info
The Lake CX403 Road Cycling Shoes – Wide represent Lake's definitive statement in road footwear — their flagship model, engineered without compromise from outsole to tongue. Built on the CX/TX RACE last with additional volume through the forefoot for riders with wider feet, the CX403 Wide delivers elite performance without the fit penalty that often pushes wider-footed riders toward less capable shoes.
The upper is Klite Kangaroo leather — lighter than bovine, naturally conforming — reinforced with Carbitex OmniFlex Carbon Fiber Stabilizer Support panels that control stretch across the midfoot and improve power transfer under load. The lining is perforated kangaroo leather, providing a smooth feel against the foot while allowing the upper to breathe. SmartFabric technology works through the liner to maintain consistent interior temperature, moderating heat during sustained efforts. The heel counter is moldable carbon, allowing a custom fit dialed precisely to your foot geometry.
The outsole is a Custom Fit Carbon Fiber sole incorporating Lake's patented double sole system — a semi-flexible inner suspended over a rigid outer plate. The inner absorbs pressure at the ball of the foot where hot spots typically develop on long efforts, while the outer delivers the stiffness needed for maximum power transfer. A replaceable heel strike pad protects the carbon when you're off the bike. Retention is handled by side-mounted BOA IP1-S Push/Pull dials, offering lateral tension distribution and the micro-adjustability the system is built for.

Design Benefits
- Wide fit without performance trade-off: The CX403 Wide carries Lake's full flagship engineering on a last shaped for wider feet — riders don't have to step down the lineup to find a shoe that fits.
- Kangaroo leather conforms over time: Klite kangaroo leather is lighter and more supple than bovine alternatives, shaping to the foot in a way synthetic materials don't replicate and maintaining that fit over years of use.
- Carbitex OmniFlex stabilizers: The OmniFlex design controls upper stretch without restricting natural foot movement, maintaining a secure fit under power without creating pressure points.
- Double sole comfort at race pace: The suspended inner sole addresses ball-of-foot pressure that leads to hot spots on long efforts — making the CX403's performance accessible across full race distances.
- Heat moldable heel: The carbon heel counter can be custom-fitted to eliminate heel slip, the primary source of power loss and fatigue in cycling shoes over extended efforts.
The CX403 Wide is what Lake builds when performance is the only constraint — a flagship road shoe for riders with wider feet who want exactly that.
The RA Perspective
We consider the CX403 to be the benchmark Lake shoe — the one we use as the reference point when customers want to understand what the brand does at its best.
The kangaroo leather is a genuine upgrade. It breaks in faster, conforms more precisely to the foot, and maintains that fit over years rather than getting sloppy. The perforated lining adds ventilation without sacrificing the feel of a leather interior, which riders notice on longer hot-weather efforts.
The Wide version is worth highlighting specifically. A lot of wider-footed riders have spent years in shoes that fit adequately but not well, because the wide options in most lineups are compromised versions of the main shoe. The CX403 Wide carries the full flagship spec — same outsole, same upper, same closure — just shaped for feet that need more room through the forefoot. We fit a lot of customers into it who didn't know Lake made a wide option at this level.
The BOA IP1-S closure is side-mounted, which is a different approach than the standard Li2 dials on the lower models. Lake made that choice deliberately for the CX403 — the side mounting distributes tension more laterally, which some riders prefer for a more even feel across the foot.
Heat molding is available and we do it in-store. Given what the CX403 costs, it's worth taking the extra step to get the heel fit right.
