u LORPEN T3 ALL SEASON TREKKER SOCK £16

You can get thicker, warmer winter socks, but the advantage of the T3 All Season Trekker is adaptability: yes it’s warm and well padded for a tough, cold winter walk but it’s also breathable and lightweight enough to see you through all the other seasons too (except possibly the height of midsummer). Plenty of cushioning, and they never slip around inside the boot. www.lorpen.co.uk
