It‘s a gentle warm air drier, with UV light. I’m not sure if it’s the thorough drying or the UV light that really makes the difference, but I suspect the drying. It seemed a bit pricey (£60ish) at the time, but cheaper than a new pair of boots, which was the only other alternative. Now all our shoes and boots (cycling and otherwise) get a turn on the drier when they’re even a little bit damp, especially if they’re needed the next day, and all the smells are gone.
