FIZIK R4 Overcurve road bicycle shoes, white

The R4 Overcurve is a professional cycling shoe from the prestigious brand Fizik, especially adapted to road cycling, it has been designed to meet your requirements during cycling expeditions. The Overcurve is a shoe construction featuring a stepped collar that wraps around the ankle, following the natural shift of two bony protrusions: the lateral and medial parts of the ankle. The result is an asymmetrical shape where the upper of the boot curves inwards. The Boa® IP1 micro-adjustable knob is an exact fit system that allows efficient, individual adjustment of the boot. The moderately stiff R4 outsole strikes a balance between comfort and pedaling performance, making it truly versatile. The inner sole profile has been structurally optimised with 15% carbon fibre composition. In addition, the R4 outsole provides effective ventilation with an internal channel for efficient thermoregulation. The threshold holes for the snap pedals are positioned slightly further towards the heel compared to the traditional position to optimise pedalling efficiency and reduce knee compression, which is particularly useful in aggressive air riding positions.
