TriPro Boa was made with the constant input of professional Triathletes. Tripro Boa is geared to the Ironman world, where the long distance in the cycling leg requires a shoe that combines the stiffness of traditional road shoes and a very quick fit to have no time loss in transition. Everything is made with a microfiber upper combined with breathable and easy-to-dry materials to shed water and keep the foot dry and comfortable. The single Boa L6 dial guarantees an excellent fit on the foot and adjustability on the fly. The Carbon Technology 2.0 sole with carbon fiber works to transfer all the power directly to the pedals without any dispersion of energy. The shoe features a strip on the heel that assists the athlete in getting the shoe on faster. The Tripro Boa features the Performance Insole, which adapts to the arch, increases power transfer on the pedals, improves comfort and reduces injury. Also available with Speedplay® specific drilling on the sole.
