SHIMANO off-road shoes feature high-quality rubber outsoles that offer great traction on various surfaces, better grip to pedal via pins, and even higher durability. The performance of off-road shoes is also heavily influenced by the pattern and quality of the rubber outsole material. Optimized Shoe Last: - 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. Spd: - SPD is a system that performs whether you’re on or off the bike, designed to meet the needs of mountain bike riding. We eliminated toe clips and integrated the pedal and outsole into a single, unified power transfer system to boost power to the pedal. It makes pedaling more efficient with a wide variety of shoe and pedal styles and the recessed cleat makes walking more comfortable. From fast-paced XC racing to steep, rocky and rooted trails, Shimano SPD pedals keep up. System-engineered. Rider-tuned.
