SPD-SL: The SPD-SL pedal system provides a seamless connection between shoe and pedal, maximizing power transfer under extreme loads. The wide cleat design enhances stability while pedaling and walking.

SHIMANO DYNALAST: Shimano Dynalast technology optimizes the toe spring area of the shoe to promote a smoother, more energy-efficient upward motion. This reduces energy loss during the backward phase of the pedal stroke (between crank angles of 200° and 360°), helping you to reduce fatigue and perform at your best on long rides. Developed based on feedback from pro riders, Dynalast helps you save energy for that final sprint to the finish line.
