Perhaps best know for the groundbreaking Aerator summer socks, Defeet also do a near-legendary winter sock, called the Woolie Boolie 2 Baaad Sheep socks. Recently upgraded to include a padded Terry loop top cuff and foot sole, plus arch compression for greater stabilisation in your shoe, they’ve made from a high percentage of merino wool (64%) so tick all the thermal, wicking and breathable boxes cyclists like. Thanks to the wonderful properties of wool, they stay warmer when they are wet than other fabrics – just what you need on dank days.

Price: £12.99, available from Evans Cycles.
