We wore them for a couple of weeks and they smelled awful. Smells like cat pee. They had a very faint smell when we received them and now after a few weeks of wearing they didn't care, the smell is so awful people around me can smell them and they are useless. They didn't get wet and we don't even have a cat. I'm not sure why this happened or if this is one of them, but they are unsustainable.
