Key Features and Benefits:
BOA Fit System with L6C dial: Allows quick, precise adjustment while riding. This ensures even pressure across the foot, giving a secure and stable fit for efficient power transfer.
Carbon fibre reinforced nylon midsole: Adds stiffness for effective energy transfer from pedal to crank. This improves acceleration and endurance by reducing wasted effort.
Integrated seamless midsole and upper: Reduces weight and improves stability. The design enhances comfort and prevents pressure points during long rides.
Low stack height midsole: Keeps the foot closer to the pedal axle, maximising efficiency. This stable platform improves control and reduces power loss.
Perforated synthetic leather upper: Boosts ventilation while offering a sleek, modern look. Riders stay cool and comfortable even in warm conditions.
Surround-wrapping upper structure: Encloses the foot evenly to minimise overlap. This ensures a glove-like fit for improved comfort and stability under load.
23% recycled materials in the toe box and midsole: Lowers environmental impact without sacrificing performance. Riders gain sustainable quality with long-lasting value.
Stiffness rating of 8: Provides a strong balance between power transfer and comfort. This supports efficient performance across varied road conditions.

Troubleshooting
BOA dial is stiff or difficult to turn
Gently clean around the dial and lace with a dry brush to remove any dirt or debris. Ensure the lace is not snagged.
Foot feels numb or experiences pressure points
Loosen the BOA dial slightly. Re-adjust the fit, ensuring the shoe is not overtightened. Consider if the shoe size is appropriate or if the cleat position needs adjustment.
Shoes feel excessively stiff and uncomfortable
For riders new to stiff-soled shoes, allow a break-in period of several rides. If discomfort persists, the stiffness rating may not suit your preference for longer durations.
Perforations in the upper seem to let in too much water
These shoes are designed for ventilation and are not waterproof. For wet conditions, consider shoe covers or alternative footwear.
