NON-REMOVABLE INSOLE. Take on any terrain in the rugged and well-built Alligator sandal from Allrounder by Mephisto. Stable, shock absorbing, and super comfortable, this river-style sandal adjusts easily with clip and hook-and-loop closures. The leather upper is lined in padded neoprene, so there's no pinching or rubbing. The cushioned anatomical footbed is removable for washing, and the durable rubber sole provides excellent traction.
