Shimano S-Phyre SH-RC903 Pwr

The S-phyre running shoes are designed for powerful sprinters looking for every possible advantage. The ideal closure system for competition with a luxurious BOA Li2 metal dial, a retention guide for the fit and a strap in the toe area reduce foot movement and improve power transfer. Run with complete confidence and let the chasers admire the dazzling, colour-changing crystals on the outsole and heel. The breathable and stretch-resistant upper keeps the foot well in place to optimise power transfer. The heel with anti-torsion stabilisation ensures optimal foot positioning for strong acceleration and high cadence. The upper part of the midsole combines with the tongue and forms like a glove to provide remarkable stability when pedalling. The flatter midsole helps stabilise the foot, optimising power transfer and efficiency. The integrated, seamless midsole and upper construction allow for a new level of customisation, stability and performance while keeping weight to a minimum.
