I guess I would say that these shoe covers work pretty well if you take their limitations into account. I had somehow thought that they would be a lot more waterproof than they are (that's what you get for not reading the description carefully!) And they are NOT!! truly anti-skid, which is a problem. You will slip and slide while wearing these. That being said, they're really good for protecting your shoes if you're working outdoors and it's not raining, and they're certainly very cheap.
