My clients have never tried to cut them off. I do know that they're uncomfortable to wear on a long-term basis. One of my clients kept getting a rash from it. He had to wear socks, and they had to change it to the other foot, so there are problems with them. I don't know how easy they are to cut, because no one's ever tried it that I know of.
