I ordered what I consider to be waterproof socks to keep my feet warm while submerging them in cold water. Everything was fine, I didn't realize these would be rubber soled shoes. I already had sandals. But I can't dive at lower leg level. You can't take it off fast enough to get warm again. I wouldn't be a very happy tourist without two pairs of very warm socks and the ability to dry quickly. But in my opinion it is not for cold water!
