TEMPO POWERSTRAP R5 is a versatile road cycling shoe with an innovative Velcro closure designed for an enveloping fit. POWERSTRAP While most Velcro closures simply pull together two sides of the shoe&';s upper, in this configuration a ribbon wraps around the foot, enabling ultimate comfort and containment using just two straps.
