The Fi'zi:k R4 Tempo Overcurve in the category of cycling shoes boasts a timeless design that conceals a cutting-edge construction technique. The shoe features a durable polyurethane laminated material combined with a comfortable mesh, ensuring lasting foot support in the necessary areas.

For a fast and secure closure, the R4 Tempo Overcurve is equipped with a microadjustable BOA IP1 dial in an Overcurve pattern. The Overcurve construction includes a staggered collar that wraps around the ankle, mimicking the natural misalignment of the ankle's two bony protrusions. This asymmetrical shape enhances the fit, with the collar curving over the foot from the outside to the inner side.

The moderately stiff R4 outsole strikes a perfect balance between comfort and pedalling efficiency, making it suitable for various riding styles. Featuring a lower profile and a composite infused with 15% carbon fiber, the R4 outsole offers optimal ventilation and internal channelling for effective temperature management. Additionally, the cleat positioning is slightly rearward compared to traditional settings, reducing knee compression and enhancing pedalling efficiency, particularly for aggressive, forward aero positions.
