These are truly life savers. I live in the Pacific Northwest, and we get a weather phenomena called freezing rain. I had never encountered this before relocating here about 17 years ago. Basically it rains Ice. Sheets and sheets of slippery, hazardous, treacherous, deadly ice. It is BALLS to attempt to go anywhere. And I don't drive. So I took many a stumble and fall before I discovered removable ice cleats. Let me tell you, these things are AMAZING. I can walk on top of the ice sheet with out slipping. Mind you, it is slow going-but just being able to safely walk to the bus stop is huge. I used to just call out on the days with freezing rain. Now I can safely make it in to work.
