Shimano's SD5 (SD501) SPD Sandals are designed for ultimate comfort during long bike-packing adventures and tours, allowing for comfortable wear on and off the bike. The improved sizing offers a better, more comfortable fit. A comfort liner allows for sock-less riding, though wearing socks is highly recommended. A cleat-cap is included for use with non-SPD flat pedals. The semi-rigid Power Transfer Blade enhances walking comfort and pedal efficiency. These sandals are lightweight, weighing just 720g per pair (size 42). The new SD5 features improved sizing and fit over the original, ensuring greater comfort on long rides. With the included cleat cap, they can be used with flat pedals if SPD pedals are not preferred. The Power Transfer Blade significantly reduces power loss for efficient pedalling and provides comfort for extended walking or hiking.
