Bests & Worsts Reviews from Amazon

First off these things DON'T grip ice, in fact if you are walking on black ice or icy sidewalks it's like walking on a wet linoleum floor. They SLIDE with no gripping. If you are walking on a lot of snow with ice underneath they would work. Next issue - the heel spike are almost under the arch of my foot even though they fit well around my boot. So you are not only sliding on ice these things throw your balance off since you can't put your heel firmly down. Would not recommend this product.
