Fizik Unisex X4 Terra Powerstrap Gravel Cycling Shoes, Mud/Caramel, 13 UK

Powerstrap X4 to be simple, efficient and reliable. In line with this approach we equipped it with the innovative Powerstrap Velcro closure, designed for an enveloping fit. While most traditional Velcro closures just pull together two sides of the shoe’s upper, in the Powerstrap configuration a ribbon wraps around the foot, providing secure containment using just two straps.

The X4 offers a carefully considered combination of stiffness and comfort, to turn pedals effectively on mixed surfaces; blending nylon – with targeted stiffness – and a rubber tread for effective grip and durability.
