Keep your feet nice and warm during the rest of this winter with these wearable cheat-codes: the insoles created by Therma Cell can be used in any of your footwear, allowing you to control the amount of desired heat wirelessly, by remote control. But how do they work, one might ask. It’s quite simple really: with batteries – rechargeable L-Ion batteries that generate a steady temperature and which can be recharged up to 500 times. One full charge makes sure you get five hours of warmth.

Oh, and don’t worry about stinky feet or sole burns – they also operate like a thermostat so once it reaches the required heat, it automatically switches off.
