SH-RC703 Shimano Road Shoes Unisex White

SHIMANO SHOES SH-RC703

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

Thanks to the thin flat crossed lacing, the forefoot is securely and elegantly fixed, while the BOA® adjustment system with two L6Z rotary closures allows for precise and individual adjustment.

The breathable synthetic leather upper offers improved fit and ventilation. The integrated and seamless midsole and upper ensure exceptional fit, stability, and lightness. The enveloping and slightly overlapping upper guarantees an optimal and snug fit. With SHIMANO DYNALAST, you will experience smooth pedaling and efficient power transfer on every ride.

*BOA System

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

*SPD SL

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

*SHIMANO DYNALAST

The spring zone of the toe of a cycling shoe plays a crucial role in enhancing pedaling efficiency. If it is too high, it can increase tension in the plantar muscles, calves, and hamstrings. If it is too low, it leads to ineffective and bent pedaling movement.

Extensive research conducted by Shimano's R&D experts has resulted in a superior shoe last design with an optimized toe spring zone that promotes a smoother and more energy-efficient upward movement. Shimano Dynalast was developed from 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.

Minimize energy loss by increasing pedaling efficiency: Between crank angles of 200° and 360°, power or energy loss occurs during the backward phase of a pedal stroke. Shoes that use Shimano Dynalast help reduce this energy loss by promoting smoother and more efficient pedaling. If you want to reduce fatigue, maximize your legs' performance, or just perform a bit better, you should pedal with Shimano Dynalast.
