Cold and slightly soggy boots aren’t the best when you’ve got a full day of adventure planned, which is where the Drywarmer Pro USB from Sidas swoops in to save the day. This little gadget will dry, disinfect and warm up your boots or shoes so that they’re ready for action again in no time. The Drywarmer has an ultraviolet light which sanitises your shoes, a vortex effect to optimise air circulation, a timer to program the dry time, and a USB socket for easy charging.
