The deck sock from AWMS is a soft top slouchy ribbed sports sock that we have been hunting high and low for. Unlike a crew sock, the wide ribbing expends all the way to the toe, like a traditional English rugby sock. This heavyweight chunky sock is made from 90% cotton, reinforced with 10% nylon, and made on a 1977 Bentley Komet sock machine from British spun cotton. British made in the heart of Leicestershire, the sockmaking capital of England. MEDIUM is suitable for UK sizes 6-9 LARGE is suitable for UK sizes 9-12
