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.
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.
A wider range of motion supports a smoother, more efficient upstroke.
