Heavy Duty Socks

Heavy Duty Socks are ideal foot protection for tough jobs outside in cold weather.

Manufactured from 100% polyamide, these socks are lightweight and soft but are exceedingly hard wearing, with a reinforced heel and flat toe seams. Unlike most other sock brands, this Sub Zero range has a non-elasticated comfort cuff finish achieved by the in-built stretch of the polyamide yarn, keeping your socks pulled up without them cutting in to your calfs. A hydrophilic treatment applied during the dyeing process also helps to manage perspiration as well as decrease drying times.

GENERAL WALKING SOCKS WASHING TIPS

Turning your walking socks inside out before washing them will help to eliminate odour causing bacteria and remove their food source - sweat and dead skin. If they are especially muddy, then think about washing them twice - once with the mud facing out and secondly turned inside out.

There have been huge advances in walking sock construction utilising numerous different blended yarns of both natural and synthetic fibres. These not only provide a better fit, longer lifespan, and shorter drying times, but also enables them to be washed at higher temperature. We would however err on the side of caution and wash all our walking socks at 30°C. 

To prevent socks being lost in the wash, many people pair them together. This often leads to poor laundry results. Instead, place your socks in a mesh washing bag.
