I have used several different styles and brands of boot studs and I like these very much. These tend to run a bit bigger than other brands so are easier to take on and off. The best feature in my opinion is that the grippers go all the way to the edges of my boot soles, eliminating the feeling of walking on top of something. They are very capable even on hard ice, and I feel confident enough to run in them. These are also the only type I would wear inside without worrying about severely damaging floors.
