The Sidi Shot shoes are a top of the range road shoes. They include a redesigned aerodynamic upper and central Tecno-3 dials that close the shoe symmetrically for a perfect custom fit.The Sidi Shot features a Vent Carbon Sole made with 3K carbon to achieve the perfect balance of rigidity and performance offering superior power transfer. The Vent Carbon Sole is designed with an integrated vent and air channels for optimized air flow. The air circulates around the channels until it escapes through the exits in the central part of the shoe. The sole also includes a sliding vent at the front which allows riders to tailor their level of airflow through the underside of the toe section.The heel retention device adds even more customization to fit via a closing system on the back of the shoe so you can tighten your heel cup to prevent slipping on steep climbs and sprints.
