This thing killed the odor from all my footwear after 2 uses. I would put my boots on it after getting home from work and rotate my shoes when leaving for work. My boots would be really damp after 12+ hours and they would be dry and ready to wear the next morning. It does put off an odd smell but not bad enough to complain. Way better than the smell of my boots. There were some 16 hour days, plus a 2 hour round trip to and from jobsite, and this boot drier still had my boots ready for me in the morning. I will have one of these for the rest of my life. Great product.
