Although I purchase it many times and use it, if I apply the medicine for athlete's foot to the foot even once, it will not become useless at all. Although it is stated in the notes, it is useless unless you paint the medicine and do not wear this shoes. Also disinfecting deodorant such as Fabrez is also prohibited. If you do not even remove bacteria, the smell will certainly disappear.
Until now, I tried using various insoles, but I was concerned about smell by all means, but when I tried using this product, surprisingly the smell decreased. To be honest, I do not completely disappear, but I think it's pretty good. After that, I actually want to use it and see how long I can withstand use.
