Our indestructible socks are specifically designed as work boot socks, to be worn under steel toe-cap boots for heavy duty, industrial and outdoor work, however over the years they have become increasingly popular with all who need hard-wearing socks. They were first advertised on television back in the 1950s, marketed as “the sock for the working man”, and they have maintained their unrivalled reputation for quality and durability over the past 60+ years.
