Our air activated insoles work WITHOUT ANY NEED FOR ELECTRICITY! Once unpacked and they have started to warm up then place them into your shoes (or slippers if inside) with the smooth side down. The cosy warmth will last for up to six hours, keeping you nice and toasty on those cold days.

Whether walking the dog, working outdoors, or watching your favourite team on a freezing cold winters day, Vytatherm insoles will keep your feet as warm as toast. We also love them when indoors too, walking around the house or just sat on the sofa.
