To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These are cute and easy to use. However, they really didn't get rid of our stinky shoe smell. The smell of whatever their active ingredient is mostly covered up the smell of stinky shoes, but it was incredibly overpowering and not particularly pleasant. After removing them from my boots, and not wearing them for a few days, the smell of these sneaker balls mostly dissipated, but the stink was back and just as strong. They also pop open easily, which is a concern with small kids that like to eat everything. They're not horrible, but I'm not a fan.
I am not sure if all of the great reviews are fake or maybe I just have abnormally smelly shoes but these do not work for me AT ALL. I put them in my shoes and all I can smell is the shoe smell and then a terribly chemical freshener smell. They do not take away the smell from the shoes. I am very disappointed.
As a fitness instructor with multiple pairs of athletic footwear, these sneaker balls have eliminated the need for sprays or the need to either wash them or throw them away because of bad odors. I've reordered these for my other shoes, and I've referred family and friends; can't say enough good things about them.
These work great. I use them in my work boots which have a tendency to stink and it takes away the odor without a lot of scent. It just neutralizes the odor. I put one in my work locker as well and it takes away the odor in there. I'll be ordering more of these when needed, but they seem to last a long while. I purchases these back in August and still using them 3 months later. I expect they have a few weeks left considering the size of the scent ball inside.
My son's shoes STINK! His soccer cleats were the worst, but he put these in his cleats as soon as he takes them off and it makes a huge difference. He uses them in all of his shoes. I will continue to purchase these!!
