Having cold feet is never pleasant, but if you’re dealing with a circulation-impeding condition such as Raynaud’s syndrome, it makes it even more crucial to have effective thermal protection. Made by SOCKSHOP and Heat Holders, these IOMI Raynaud's 3.1 TOG Striped Thermal Slipper Socks ensure warmth for your feet and help keep your blood flowing properly, to alleviate the symptoms. Some of the warmest socks produced by Heat Holders, these men’s thermal slipper socks have a dual layer design which super-charges their performance to double the insulating ability.  As with all Heat Holders, made from advanced, Japanese designed thermally insulating yarn, the innermost layer is a cushioned terry looped, expertly brushed into a bed of fibres that catch and hold warm air. The twin layer combines the properties of two pairs of Heat Holders Lite socks into one slipper sock that measures 3.1 TOG — a rating that is over 9 x warmer than a basic cotton sock! The double layer creates a unique thermal cavity capable of holding even more warm air. Outside the socks, slip-resisting treads on the soles make them ideal for wearing around the home. There’s no better, easier way to make sure your feet stay toasty and your circulation is protected. Non-binding tops are added to these slipper socks to further protect your circulation.
