I put mine in a small closet with a dehumidifier after I put a washcloth in it to soak up as much moisture as possible. Then, take out the cloth and let the boots sit in front of the dehumidifier. They're dry by morning.
I've got a pair of 3 mil. split toe ripcurl f-bombs more for mid-late spring and fall. I recently also purchased a pair of 5 mil. full toe booties for RI winter at a tag sale for 10 bucks. Great condition, its like they've only been used once. Both my pairs dry pretty fast in front of my woodstove or on my radiator. They're dry by the next day for sure. (The brand on the 5 mils is some non-popular brand I've never even heard of) but they're great overall.
I love the 7 ml Xcel drylock booties. My feet are toasty all the time and worth the expense. Have to admit it took a few times out to get used to more rubber under my feet. Great idea putting a dry towel inside to bootie to hasten drying.
