i use something rather like this,
http://www.dryguy.net/DG1.html
can’t remember the brand, cost around £40 from europe, very gentle heat, dries out even waterlogged MW80’s in about 3 hours. We have no cental heating and wife doesn’t like the smell of 3 pairs of wet boots by the fire for 2 days at a time. ( me and kids)
I can leave it in the garage on a timer overnight, probs solved. If i was buying again i’d look or one that did 2 pairs at once if possible, mine only does one pair.
tried virtually everything else, inc Absorballs etc( Rubbish for me), wouldn’t waste my tiem with anything else as i ride regualr through the winter regardles of conditions and knowing you’ve got clean dry kit the next day is a boon. the stitching also lasts longer if it’s not sat rotting.
