Pro Carbon Cycling Triathlon Shoes. The construction uses an ultra-lightweight carbon outsole to achieve excellent power transfer during pedaling and the lowest weight possible. Ultra-light PU is upper with perforated construction and ventilation systems for better foot ventilation. Fixation of the foot is carried out with the help of power straps with Velcro, allowing you to leave the Pro Carbon Cycling Triathlon Shoes as open as possible. Then you can firmly fix the shoe on your foot. The special design of the heel part will not allow you to slip out for the first meters of the distance after the transit zone.
