Heat Holders Thermal Socks have got to be the cosiest socks I’ve ever worn! The socks have a 2.3 Tog rating and are meant to keep your feet seven times warmer than normal socks. I’ve got a pair of long length socks which are really soft and fluffy inside making them very comfy and keeping me toasty all the way up to my knees. The socks are also not as bulky as my other pair of thermal socks which is good as they are easier to wear under clothes. These socks are perfect for anyone who, like me, always seems to have freezing cold feet – I don’t want to have to take them off ever again!
