Does seem to work on my shoes. The recommendation is to remove the insole before spraying so just keep in mind that you'll be removing/reinserting it. My insoles are soaked in this FL heat where the heat index is at or above 100 degrees. I spray it in my gym bag and it works there too.

This is a must-have product for anyone who works out. Although my workout days are long behind me, I still wear sneakers every day for walking and biking. 2Toms does a great job of keeping those shoes fresh and ready for the next day and it even allows me to keep my sneakers in the closet rather than in the garage...and I'm sure you know what I mean! Get some...you will love it!

I spray this on the inside of the shoe after use and let it dry before using shoes again. Over a period of several days of this routine the shoe stink is almost gone and manageable. This stuff works on my running shoes, golf shoes, work shoes and casuals. I'm no longer embarrassed by my foot odor. I was all set to toss the smelly shoes but decided to give the product a shot...I'm glad I did and so are my wife and friends!
