Due to this close bond between sock cuff and skin, we recommend that Hydrostop socks are only used outdoors and not for a prolonged period of time. Incorrect or prolonged use can result in excessive rubbing against the skin and may in a very small minority of cases cause minor skin irritation. The Hydrostop seal material has been fully tested to EN ISO 10993-5: 2009 and is OEKOTEX compliant.
