They are great IF you can keep them on your shoes. I even put them on very carefully on a specific shoe so I wouldn't take them on and off and that I would know it was on each shoe as well as it could be. I wore them twice and lost and found the one that came off the first time. The second time it came off it was gone. If you are in snow/ice all the time, they are fine, but if you get off onto pavement they come off.
