My family and I used these cleats all this last
winter (winter of 2009-2010). We got an enormous
amout of snow this last winter and these cleats
allowed us to keep walking on trails near our
house all winter. Even though, we typically
walked an hour a day on mixed packed snow, ice
and rock, the cleats show no wear.
Pros: Work great on packed snow and some ice.
Cons: If you walk mostly on ice, you may want
something with more metal on the bottom.
