SHIMANO SH-RC703

The Shimano SH-RC703 road cycling shoe is a high-performance road racing shoe that is equipped with S-PHYRE DNA and meets the highest demands. The hollow carbon midsole ensures maximum power transfer, efficient ventilation and rapid water drainage thanks to its high stiffness.

Thanks to the thin, flat cross lacing, the forefoot is securely and elegantly locked in place, while the BOA fit system with two L6Z rotating closures allows for a precise, individual fit.

The breathable synthetic leather upper offers improved fit and ventilation. The seamless, integrated midsole and vamp ensure exceptional fit, stability and lightness. The wraparound, low-overlap upper ensures an optimal, snug fit. With SHIMANO DYNALAST, you’ll experience smooth pedaling and efficient power transfer on every ride.

*BOA system

The Boa system offers infinitely variable adjustment for a perfect fit. One-hand adjustment, secure tightening and quick release.

*SPD SL

The SPD-SL pedal system offers a seamless connection between the shoe and pedal for more efficient power transmission under extreme pedaling loads with a wide cleat design for greater stability when pedaling and walking.

*SHIMANO DYNALAST

The spring zone of a cycling shoe’s toe box plays a key role in promoting pedaling efficiency. If it’s too high, it can cause increased stress on the plantar, calf and hamstring muscles. If it’s too low, it causes a flexed and inefficient pedaling motion.

Extensive research by Shimanos R&D experts has resulted in a superior shoe last design with an optimised toe spring zone that promotes a smoother, more energy-efficient upward motion. Shimano Dynalast was developed based on feedback from professional cyclists and helps reduce energy loss on long rides. This gives you more power for the final sprint across the finish line.

Limit energy loss by increasing pedaling efficiency: Between crank angles of 200 and 360, there is a loss of power or energy in the backswing phase of a pedal stroke. Shoes using Shimano Dynalast help reduce this energy loss by promoting a smoother, more efficient pedaling motion. If you want to reduce fatigue, get the most out of your legs, or just perform a little better, you should be pedaling with Shimano Dynalast.
