Bought these after 6" of snow turned into 2" of ice. Used them daily to walk the dog and get the mail down our 200yd drive. They do work. I didn't run or jog and it was mainly flat ground. Sometimes snow will  fill up in them but for the most part they were good. I stayed upright. Problem is after 3 weeks the back coil on one broke. A week later same on the other. I can still use them but I have to be careful getting ready to go out becasue they will catch and pull on rugs. I have 6 weeks of possible ice to go and I hope they last. I know they were around $25 but I think everything should last more than 3 weeks
It is now 2 weeks after my original review. Yesterday the strap on the heel holding the cleats broke. I am stil using them because we still have the ice from Feb. We seem to be getting more ice each year in Vt than we used to so I will probably need something like these next year...but it won't be this brand
