37.5 (24cm) Sole: Carbon reinforced nylon Upper: Microtex Closing System: POWERSTRAP TEMPO: A versatile road series for the most comfortable ride. ROAD: Design and technology that performs on all paved surfaces, from smooth roads to harsh pavé. R5 Nylon Composite Outsole: Achieves a balance of high comfort and excellent pedaling efficiency. POWERSTRAP: The foot-wrap Velcro closure, designed to envelop the entire foot, provides riders with a superior fit and an original, stylish look. Versatile road cycling shoes with innovative Velcro closure. While most Velcro closures simply pull the two sides of the upper together, the POWERSTRAP configuration uses a ribbon-like thick strap that wraps around the foot, achieving ultimate comfort and fit with just two straps. This system replicates the volume control of fizi:k and can be adjusted for a superior fit for various foot shapes. [Notes on Cleat Installation] Depending on the manufacturer of the cleats used and the shoe size, the curve of the cleat may not match the curve of the outsole. Forcing installation may damage the cleat or make it difficult to secure to the pedal due to cleat flex. In such cases, please prepare a spacer to fill the gap between the outsole and the cleat and make adjustments as needed. (fizi:k does not offer spacers.)
