Men's and women's waterproof ankle length sock, enforced with Hydrostop™. Highly breathable, the Dunton thrives in multiple environments. Hydrostop™ prevents water dripping down leg into sock. Handcrafted in the Sealskinz factory in Norfolk. Please note that due to the close bond between sock cuff and skin, over prolonged use, some people may experience minor skin irritation due to the Hydrostop™ barrier rubbing against the skin. For those who experience any irritation, we recommend that Hydrostop™ socks are only used outdoors and not for a prolonged period of time.
