Query: no more slipping on the ice!

These are the best thing to come along since sliced bread! I was always afraid to walk to my car or the mailbox any time there was some ice on the sidewalk and road. I've slipped and injured myself too many times. The first time I tried these, my sidewalk was a sheet of ice. I not only didn't fall, I didn't slip once! The person who invented these deserves a medal!
