I use these cleats every day around the farm, in the Wisconsin winter. The livestock packs the snow down into ice, and the footing is treacherous. These cleats last the entire season, stay in place on my boots, and work beautifully. The only reason that I have to replace them is that over time, the teeth on the cleats get a bit dull. At this price, it's reasonable to just replace them. I have been using them for about 8 years, and although I have tried other brands, I always come back to these.
