Once you have followed others advice, you can avoid a recurrence of the problem in a couple of ways.

1. prop the boots up next to a dehumidifier so that air can circulate all around them until they dry. Loosen the laces and pull the tongue outward to facilitate drying.

2. if your clothes dryer has an "air dry" feature, consider putting your clean boots on the rack and letting the dryer run for a while. Ours will blow air without tumbling so you can dry sweaters flat, for instance.

If yours won't do that, you can jerry rig a mesh bag to the inside of the door and let the dryer run until the boots are dry. I would not recommend high heat for the sake of any rubber or elastic elements in the boots.

3. a hint for us girlies: spray the insides of the boots and the outside of your stocking feet with a mixture of 2/3 cups of vodka, 15 drops lavendar essential oil and 10 drops of lemon essential oil. For more powerful stank use tea tree, eucalyptus and or manuka.
