Tender’s Underground socks are knitted and hand linked in England from unbleached wool, with nylon for durability, before dyeing as whole pieces. This pattern was originally made for socks produced for London Underground tunnel maintenance staff, who work in the off hours after the last trains. They are very soft, warm, and substantial and can be worn even in very cold weather.

Traditional hosiery like this is knitted as a long continuous tube of many socks, which are then cut apart into individual socks. These are then linked, which means that the open sock has the two sides knitted together, leaving a flat, seamless, join at the toe. Linking requires the operator to loop every corresponding stitch of the top and bottom of the sock, by hand, onto a knitting machine.

Please note that the colour in natural dyed socks may transfer for the first few wears- we recommend washing cool, with similar colours, and not wearing with light coloured shoes until the socks have been washed.
