Lake Women's CX400 Road Cycling Shoes
Perfect for competitive female cyclists, the CX400 Women's Road Shoes combine Lake’s heritage of innovation with a shoe that balances efficiency, comfort, and race-ready performance.
Lightweight, Breathable, and Durable Upper
The Women's CX400 upper is crafted from Clarino® microfiber with strategically placed perforations, providing a lightweight, breathable, and durable structure. Clarino replicates the supple, form-fitting qualities of natural leather while resisting stretch and environmental wear, ensuring a consistent fit over time. The design supports natural foot biomechanics while maintaining a secure hold, making it ideal for long rides and high-intensity efforts alike.
Full Carbon Sole for Maximum Power Transfer
Featuring a full carbon fibre sole, the CX400 is engineered to deliver stiffness where it matters and controlled flex where comfort is critical. Its construction adapts naturally to the rider’s foot shape, eliminating the need for heat moulding while providing race-level power transfer and long-ride comfort.
Integrated Dual BOA® Fit System for Precision Adjustment
The BOA® Li2 Push/Pull dial system integrates seamlessly into Lake’s expertly designed upper, allowing micro-adjustments for a secure, glove-like fit. Combined with Lake’s precise last, superior upper materials, and expert design, the dual BOA system ensures unmatched comfort, stability, and performance across every pedal stroke.
Pedal Compatibility
These cycling shoes are compatible with road pedal systems that utilise the 3-bolt cleat system, such as Shimano SPD SL, Look Keo/Blade, Time Atac, etc...

Take your foot measurement in a standing position while wearing your cycling socks.
Step 1: Trace your foot onto a sheet of paper. After you trace your foot take a ruler and make a line to mark the furthest point on all four sides as shown below.
Step 2: Length measurement (Points 1 to 2 as shown below). Use a millimeter ruler to get the measurement of the longest distance from heel to longest toe (first or second toe).
Step 3: Width measurement (Points 3 to 4 as shown below). Use a millimeter ruler to get the measurement of the widest distance of foot from side to side.
Step 4: Repeat steps for other foot as your feet may be different sizes. Typically you will want shoes that accommodate your largest foot the most comfortably.
*Add +5mm to your measured length to get correct shoe length.
