Did what I asked of them to be fair. I tested it in the tub before taking them out into the real world and I go kayaking multiple times a week. They were waterproof until the water level reached about halfway up my shin. Just where the main color meets the upper color is where the liner ends so I felt water begin to deep down my legs inside the socks. I stepped out of the tub and took them off and sure enough, my ankle was moist, not wet but not dry, and my feet were still dry. So I’d say they are good for hiking in water higher than the foot but not all the way up the sock. Did great and I didn’t expect them to stop water from getting in over the top so they did what they were supposed to do and nothing more. Hopefully this helps!
