THMO Rainbow Thermal Socks THMO thermal socks have been made with a heavy bulk acrylic yarn with extreme thermal qualities. They have been double brushed on the inside to maximise warmth by trapping warm air and keeping it close to your feet. This brushing also softens the inside of the sock making it a great choice for keeping you warm. The funky and bright striped rainbow design of these socks are perfect if you want to jazz up your feet around the house. It also makes them a must-have for your sock drawer. These thermal socks also feel like they are seamless with a neat hand-linked toe. Our innovative ribbed extra stretch welt at the top of the sock has been designed to rest to the natural contours of your legs. This wide soft top provides all day comfort and will reduce the chances of nasty constriction rings developing around your legs. The THMO badge is also heat transferred onto the side of the sock. These THMO socks are available in a rainbow colour. They are available in 2 sizes - Men’s 6-11 UK 39-45 Eur 7-12 US and Ladies 4-8 UK 37-42 Eur 5-8 US. They are made from 93% Acrylic, 7% Polyamide.
