Shimano's SD5 (SD501) SPD Sandals are a true icon, offering the ultimate in comfort for touring, bike-packing, and long adventures where comfortable all-day wear, on or off the bike, is essential. These sandals feature improved sizing for a better fit, a comfort liner for sock-less riding (though socks are recommended), and a cleat-cap for use with non-SPD flat pedals. The semi-rigid Power Transfer Blade enhances walking comfort and provides efficient pedalling with reduced power loss. Weighing just 720g per pair (size 42) and with a stiffness rating of 4, they are designed for maximum performance and comfort. The original design has been updated for even greater comfort on long rides.
