Lake CX400-X Wide Road Shoe

Description

Power, Precision, & Performance

Reviving one of their most iconic performance platforms, the Lake CX400-X evolves from the original moldable design into a more streamlined, race-driven shoe built on Lake's Race last. It delivers pro-level stiffness and stability through a refined carbon chassis, paired with an anatomically supportive fit that is ready to perform immediately. Designed to simplify setup while preserving Lake's heritage of innovation, the CX400-X provides a stable and efficient foundation for competitive cycling.

The CX400-X shares the same monocoque carbon construction as the CX403, where the upper wraps around an integrated carbon sole and heel counter. Compared to traditional Race Last models, this construction adds fixed internal volume, which may feel slightly roomier than models such as the CX333 in a similar size and width.

Unlike the CX403, the CX400-X incorporates engineered flex through the heel structure, allowing a comfortable out-of-box fit without heat molding. This creates a slightly less aggressive heel hold while maintaining excellent stability due to the integrated carbon platform.

Riders seeking strong performance support with improved immediate comfort often prefer this construction. If you are between sizes or prefer additional room, consider sizing up 0.5–1 size.

Features:

• Fit and intent: Designed to simplify setup while preserving Lake's heritage of innovation, the CX400-X provides a stable, efficient foundation for competitive cycling.
• Please note: The CX400-X CANNOT be heat molded.
• Last: CX/TX Race last – slightly narrower toe box and tighter heel than the Competition last with less overall volume than the Sport last, designed for very high-cadence riding with a slimmer fit.
• Outsole: Full carbon fiber sole engineered for stiffness where needed and controlled flex where comfort is critical, naturally adapting to the rider's foot shape to provide race-level power transfer and all-day comfort without heat molding.
• Upper: Clarino microfiber upper with strategically placed perforations for a lightweight, breathable construction that resists stretch and environmental wear while maintaining structural integrity and long-ride comfort.
• Upper support: Engineered to support natural biomechanics and provide a secure hold for high-intensity efforts while retaining a supple, form-fitting feel.
• Closure: Dual BOA® Fit System with Li2 push/pull dials integrated into Lake's upper design for precise, even tension and rapid adjustability.
• Fit system design: Lake's in-house last design, patterning, upper materials, and BOA integration combine to deliver an exceptionally comfortable, performance-focused fit.
