POWERSTRAP X4 is a versatile and ubiquitous gravel-focused shoe, designed for drop-bar riders whose adventures and aspirations take them beyond the traditional paved roads.  Mixing terrain, grinding gravel or gliding through flowy singletrack: these shoes are designed to take you where regular road shoes can't.  To suit what today's gravel-orientated adventure cyclists want, fizik designed the Powerstrap X4 to be simple, efficient and reliable. In line with this approach they 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' upper, in the Powerstrap configuration a ribbon wraps around the foot, providing secure containment using just two straps. The instep and the midfoot are separately adjustable for customized fit and compression.  For these versatile shoes fizik developed a specific outsole, the X4: 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.

• X4 nylon outsole - with rubber tread, stiffness index 6
• Weight: 292g (size 42- 1/2 pair)
• Powerstrap: foot-wrapping Velcro closure designed for an enveloping fit
