Shoe/boot Ice grippers, anyone used them before?

Those things Belmit linked look awesome - I could do with a pair. I have a tendency to say hello to icy surfaces with my bottom fairly regularly

I bought some of these after reading reviews, and you can replace the cleats which gives them better life expectancy, should keep me upright, be able to take the kids out in the snow too .
