Stink Eater Muncher Natural Enzyme Shoe Deodorizer Spray, Foot Odor Eliminator & Freshener | Wipe Out the Cause Of Smells At Their Source

This works very well. It even worked on cat urine.

The fact that it is all natural is great and especially that it is aluminum free which is very important. But unfortunately it just did not work to remove the odor from the insert of my sneakers. The odor was not that strong to begin with. I sprayed it numerous times but it did not reduce the odor at all. Maybe because it didn't really penetrate the material which looks like a spongy material covered with cloth. I will try to use it for other odors but for the shoes it did not help at all.
