SOCKS

81:2010 Determination Of Whole Shoe Thermal Insulation Value And Cold Rating A cold rating test to assess thermal performance. The itemof footwear is tested on a heated artificial foot form and by monitoring the amount of energy required to maintain the foot temperature and the temperature of the foot and its surrounding environment, a range of minimum temperatures at which the footwear will feel comfortable according to the activity level of the wearer can be calculated. To test socks, a reference sample of footwear (FW11) is first tested with a reference sock and then with the sample sock (SK18) to assess the contribution made to the thermal performance of the footwear. Unisex Sock Range The unisex range of workwear socks come in a variety of styles and colour. Features include reinforced heels and toes for durability and a cushion sole area providing extra comfort and warmth.
