CX403 Speedplay Cycling Shoe

Lake’s top-tier road shoe gets an update in the new CX403. Featuring the same custom fit carbon fiber sole and supple kangaroo leather upper as its predecessor, the CX403’s BOA closure system is redesigned and the added rubber toe bumper helps extend the shoe’s longevity. These CX403 Shoes are offered in a Speedplay-specific sole, eliminating the need for adapter base plates and lowering the stack height for improved power transfer.

Lake’s Custom Fit carbon soles are heat-moldable, ensuring the perfect fit and incredible heel hold. Compared to the CX402, the CX403’s instep strap is twice as wide to better disperse pressure from the upper BOA dial. By employing two Boa dials, Lake enables you to keep your heel locked down, without requiring undue pressure on the forefoot. And as you already know, that means better blood flow, and greater comfort.

  • Unrivaled cycling shoes for the discerning racer
  • Stiff carbon sole can be heat-molded to your foot
  • Speedplay-specific sole eliminates need for adapters
  • Kangaroo leather is supple and forms to foot
  • Dual Boa closures dial fit without undue weight gain or bulk

Stiff Shoe!

I've used it several times
True to size
Size Bought
48 (14)

I have only used them two times (one was a 50+ mile ride with 4000+ ft of climb) but the initial feel was a very stiff and comfortable shoe! It is also easy to get on & off, which some shoes, I need a shoe horn! I liked my current shoes (Mavic's) as the heal felt solid but the Lakes are great on the heal and very solid out of the saddle. I also run Speedplay cleats which work very well on this Speedplay specific shoe.......like less stack! I didn't adjust my seat and my knees feel fine, I must have had my saddle a little low. Sizing is great, I am abiut a 13.5 and got a 14 which works well. They are a little difficult to walk in but I think I'll get used to that. Heartily recommend!

Hi Gregory G. Did you use the Speedplay Walkable Cleat Protector Shim Kit with your setup? If you did, where did you find them? Cheers, Marc B.
