Deodorizing work boots or sneakers calls for strong stuff!
Simply slip a new dryer fabric softener sheet into each smelly shoe and leave it in overnight to cancel out odors (just remember to pull them out before wearing the shoes).
It’s also a smart idea to freshen and deodorize places where you store your shoes. Drop a dryer sheet into the bottom of a shoe rack or boot tray and leave it there until your nose lets you know it’s time to renew it. Use dryer sheets to freshen these other items.
