Hilly Unisex Marathon Fresh Anklet Min - Cobalt/Iron

The unique ingredient in these socks is the Polygiene® technology. Made with low concentrations of silver salt, which has anti-microbial properties and is naturally present in water and soil, to safely eliminate the ability of bacteria and fungi to grow. This is only active on the sock itself and does not interfere with the skin's bacterial flora. The added benefit of Polygiene® and odour control will not wash out as the technology is bound and permanently integrated into the sock. The Marathon Fresh is also made with LYCRA® SPORT fibre to ensure a close, comfortable fit. Socks are designed and manufactured by HILLY, the UK's premier technical performance sock company for runners - founded by Ron Hill. Polygiene® – permanent odour control
