Shimano recommends the following combination for a "perfect match":
The SPD-SL pedal system delivers a seamless shoe + pedal interface for more efficient power transfer under extreme pedaling loads, with a wide cleat design for stability on or off the bike. Learn more about the SPD-SL system!
The Boa® System offers infinite adjustment for glove-like fit. On-the-fly, one-handed adjustments, secure locking and fast release.
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 last 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.
Cut braking loss with more efficient pedaling. Braking loss is the unwanted loss of power that occurs between the crank angles of 200° and 360° in the backspin direction of a pedal stroke. Shoes incorporating Shimano Dynalast help to reduce braking loss by promoting smoother, more efficient pedaling. If you want to reduce fatigue, get the most out of your legs, and go the extra mile, ride Shimano Dynalast.

Ordered size 43 (27,2 cm). Shoes are good quality and are very comfortable. They are great for seated easy-medium rides but a soon as you're out of the saddle or start to push some serious watts, they are too soft.
