I wear two sets of high top boots and work on hard concrete all day, in a hot, humid shop.

My boots spend a day on this dryer, then worn a day. This works magnificently.

Also does a great job helping eliminate pesky athletes foot by helping kill it off from inside the boot.

I recommend keeping a spray bottle of straight household vinegar next to it. Spritz the inside of the boots, let it soak in a little, and drop it on this dryer. This helps kill off the fungus. I also spray my feet with it, but if its really itchy, you better grab the altar by the horns before you spray them.
