To use these wetsuit boots, simply slip your feet in. They're designed to fit snugly but comfortably. When you're out in the cold water, they'll keep your feet warm. After use, rinse them with fresh water to remove salt and sand. Hang them in a cool, dry place away from direct sunlight. Avoid sharp objects that could tear the neoprene. And don't leave them in a wet or dirty state for too long, as this could damage the material.
