Shimano S-Phire Road SH-RC902 Shoe No makeup. No gimmicks just pure scientifically driven design: Comfort shouldn't be an afterthought. How a shoe fits and feels defines its performance. S Phyre Rc902 literally fits into another dimension With its new 360 ° wraparound upper, function specific zones, anti-twist stabilizer and refined Dynalast profile. Its highly engineered fit minimizes energy loss and maximizes power transfer for Pro-level performance that feels and functions unlike anything you've ever worn before. 360 ° wraparound upper evolution of an engineered fit: A first for a Shimano shoe, our new 360 ° upper wraps the foot in a cocoon of support from the upper all the way around the sole. We have overcome many material and engineering obstacles to create this revolutionary structure that creates a highly engineered fit, unprecedented stability and lightweight performance for all riders. Function-specific zones Optimal stiffness and flexibility: Reinforced mesh and microfiber leather upper materials are layered in targeted performance zones to maximize fit, flexibility, stiffness and breathability. It took equal parts of science and art to complete this engineering puzzle. Anti-torsion stabilizer that accelerates performance: The anti-torsion stabilizer is built to handle the intense twisting forces caused by explosive acceleration. We used foot motion studies and pedaling visualizations to redesign the structure of the shoe to support more aggressive acceleration. Refined Dynalast profile Superior fit for all cyclists: When striving to create the best cycling shoe possible, every degree and mm matters. New rounds of rider feedback helped us sculpt the latest last for a more comfortable forefoot fit.
