ok so its not really an invention seeing as they already make them, but some one seriously needs to do a better job at making cat tracks, as in the rubber things you put on your boots to stop the soles form wearing down. They fucking suck, they pop off all the time, especially once youve had them for a bit and they get a bit stretched out. I know they make like big expensive hard ones, but those are so big that you cant put them into your jacket easily. So if someone could just redesign cat tracks and make them not suck, that would superb.
