POWERSTRAP: Traditional Velcro closures simply bring together the two sides of the shoe's upper, but the Powerstrap configuration uses a ribbon to wrap around the foot with just two straps. The instep and midfoot can be adjusted individually for a customized fit and compression.
X4 OUTSOLE: We developed a specific outsole, the X4, for these versatile shoes. It is a carefully considered combination of stiffness and comfort for effective pedal turning on mixed surfaces, blending nylon with targeted stiffness and a rubber tread for grip and durability.
