They work!
These little things really work! I've been quite pleased with them. I put them in all of my summer work sandals that have the cloth footbed that tends to get sticky. They've worked great! My only complaint is that they don't have any sticky on them. They have a non-slip back to them and it works ok, but sometimes when walking I have to stop and adjust them because they've migrated in my shoe and bunched up under my toes. It doesn't happen that often, but when it does it's very annoying. It won't stop me from using these, though! They are great for the shoes that the odor eaters won't fit in!
