It is amazing how far technology has come – my dad’s 25 year old waterproof socks feel and look like shells! These feel exactly like normal cotton socks, extremely comfy and NO way you could get a blister. They are very much waterPROOF as I have fully submerged them whilst river wading. If water goes above the ankle line it seeps in – but that is to be expected. However, the seal is great so that rainwater wouldn’t soak your toes, only when the sock is fully submerged does the water enter.
