They are not waterproof! Anything more than a couple of heavy splashes and the water will seep into the Pitards (sp?) leather outer. I guess you could seal them with something, but I've never felt the need. Where they really shine is when the temperature gets below freezing and water turns to snow/ice. Went on a 90 minute ride tonight in 5 F weather. Feet were toasty, if not my hands.
