Battle cold weather like it’s a super-villain! Bring on the good guys of insulated protection — SOCKSHOP Heat Holders Marvel 1.6 TOG Lite Iron Man and Captain America Thermal Socks can keep you warm without effort, delivering a thermal beat-down to evil frozen feet! And, it’s all done in a Heat Holders Lite thickness format, so you don’t need big, bulky boots to wear them, they fit into standard shoes and boots comfortably, without the super-thick feel of original maximum thickness Heat Holders. Measured to an official 1.6 TOG rating for warmth, they are four times warmer than a basic cotton sock! Not designed by Tony Stark, but our own Heat Holders super-geniuses, this TOG (Thermal Overall Grade) rating is achieved by crafting the socks from Heat Holders’ advanced, Japanese-designed thermal yarn. It’s a high performance insulating yarn that is knitted with a medium-length looped pile inside, which is then expertly brushed in a process that creates thousands and thousands of fluffy, super-soft fibres that aren’t just designed to cushion the feet, but to capture and hold in warm air, keeping it close to the skin for long-lasting warmth. Heat Holders are made to be non-binding too, holding to the legs without tightness. This means they are ideal for diabetics, and can provide relief for anyone suffering cold feet due to circulation problems. Heat Holders in partnership with The Sleep Charity.
