Due to this close bond between sock cuff & skin, we recommend that Hydrostop socks are only used outdoors & not for a prolonged period of time. Incorrect or prolonged use can result in excessive rubbing against the skin & 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 & is OEKOTEX compliant. 40d-tumble
