Featherweight gravel racing shoes. Technologies Shimano Pedaling Dynamics – SPD is a system that performs whether you’re on or off the bike. It makes pedaling more efficient with a wide variety of shoe and pedal styles and the recess cleat makes walking more comfortable. You can pedal with greater efficiency, stability and comfort with the SPD system. 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 last design with an optimised 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. Expanded Cleat-Adjustment Range – Set the initial cleat position according to the difference between shoe size and measured arch length. If the arch length is longer or shorter than the shoe size, the cleat maybe positioned fore or aft from the center line of the cleat range of the shoe by the difference of the scale. *For example, if the right shoe size is 43 and the arch length measurement is 44, the cleat should be positioned (distance A) forward, toward the toe end, from the cleat range center line of the shoe sole. Upper Technology – The construction of their uppers and closure systems are customised to the characteristics of each rider’s foot. Their Surround Wrapping Upper surrounds the whole foot with a seamless piece of leather, which creates a better fit with fewer gaps between shoes and feet. Features Super stiff and lightweight carbon composite sole. System engineered with SPD pedals for maximum pedaling efficiency and stability. Lightweight, abrasion-resistant TPU lugs for the best balance of pedaling performance and off the bike capability.
