A perfect fit for perfect power transfer: Two disc closures mould the shoe to the foot like a second skin for optimum pressure distribution. The stiff CUBE carbon outsole transmits power with maximum efficiency while the CUBE Anti-Slip System keeps the heel firmly in place for your best performance yet! Optimum climate control comes courtesy of an intelligent mix of dirt-repellent upper and ventilated tongue. The asymmetrical design minimises the potential for pressure points and reflective details guarantee added safety.
