Technology:

Shimano Dynalast
The toe-spring section of a cycling shoe plays a key role in supporting efficient pedaling. Too high, and it causes increased tension in the plantar, calf, and hamstring muscles. Too low, and you get a bowlegged, inefficient pedaling form. Extensive research by Shimano’s R&D experts has produced a superior shoe design with an optimized toe-spring section that promotes a smoother, more energy-efficient upstroke. Built based on feedback from pro riders, Shimano Dynalast helps reduce energy loss on long rides, letting you keep more in the tank for that final sprint to the line.

BOA
Boa closures offer infinite adjustment for a glove-like fit. On-the-fly, one-handed adjustments, secure locking, and fast release. Sheds mud and water while saving weight.

Avail 100
While being flexible, Teijin Avail 100 also provides a highly rigid fit. Power loss is reduced and pedaling efficiency is improved, thanks to this material’s superior shape-retention characteristics and a rigid layer that suppresses elongation.

S-Phyre
S-Phyre is the new top model by Shimano in shoe wear. The SH-RC9 is the top shoe for road races with great long-distance comfort and unbelievable efficiency. The main characteristics are:
High-performance one-piece cover:
The one-piece outer on S-PHYRE footwear is made from supple, stretch-resistant and highly breathable Teijin Avail microfiber synthetic leather with perforated dimple vents, that are even more flexible, providing a glove-like fit.
Dual Micro-Adjust Lacing: The Boa-IP1 dials allow a highly tuneable fit and the Boa power zone wire guide is adjustable to help maintain consistent tension along the top of the foot.
Asymmetric Control: Asymmetric eye-stay pattern prevents twisting of the foot under high-power pedaling.
One-Piece Upper: One-piece upper design provides a glove-like fit.
Seamless Midsole: Elimination of the lasting board reduces weight and enables a lower stack height to help stabilize the foot and maximize power output.
Low Stack Height: Low stack height helps stabilize your foot during the downward pedaling stroke.
Carbon Outsole: Ultra-rigid lightweight carbon sole maximizes power transfer.
External Heel Cup: External curved heel cup construction suppresses foot twist and roll, stabilizes the heel and holds your foot firmly in place.
Extended Range Cleat Adjustment: Extra 11 mm of cleat adjustment range.

Size Guide:

Shimano shoes (except the GORE-TEX&trade models) have a narrowed form and may be smaller than expected. The best solution is to order one size larger than usual.
