Extremely durable and comfortable sock. 70% Merino wool, 26% nylon and 4% lycra. The Y heel construction with the lycra and arch support maintains a correct fit,while the reinforced heel, toe and sole provide comfort and reduce fatigue. M = 5.5 – 7.5 UK, L = 8 – 10.5 UK, XL = 11 – 13.5 Check the size carefully. We do not believe you will find a more durable, warmer or more comfortable sock. Proven on my 4 trips to Kokoda.
