Sub Zero Merino Wool Blend Thermal Walking Socks are manufactured from a blended yarn of premium Spanish Merino wool and virgin Polyamide. This produces a finished sock that is very soft and insulating, with excellent moisture management and anti-bacterial properties. The addition of Polyamide also reduces the friction within your foot that could otherwise lead to blisters and sores.

The half Terry foot construction provides underfoot cushioning loops for impact protection and insulation, whilst the technical toe construction provides a non-irritating smooth seam for added comfort. Unlike most other sock brands, the Sub Zero range has a non-elasticated comfort cuff finish achieved by the in-built stretch of the Polyamide yarn. This will keep your socks pulled up without them cutting in to your calfs.

A water repellent treatment called Rucodry Eco is applied to the socks during the final stages of manufacturing, providing outstanding moisture management and stain resistance.

Sub Zero Merino wool blend thermal walking socks are ideal for backpacking, trekking and hiking trips in all weather conditions.

Brilliant socks - come up very big

Love love love these socks. Soft and warm and great quality. I'm a UK size 7-8 and even the small socks are roomy on me. So order small to avoid disappointment.
