Shimano's SD5 (SD501) SPD Sandals are a true icon for riders who seek ultimate comfort during touring and long bike-packing adventures. These sandals are perfect for all-day wear, on or off the bike. The improved sizing offers a better, more comfortable fit. A comfort liner allows for sock-less riding, although wearing socks is still highly recommended. For those who don't use SPD pedals, a cleat cap is included, allowing the shoes to be used with flat pedals. The semi-rigid Power Transfer Blade ensures significant power-loss reduction for efficient pedalling and comfortable walking for extended periods, even during hiking. Lightweight at just 720g per pair (size 42) with a stiffness rating of 4.
