Wow wow wow!!!  We got these recently and after just ONE HIKE using them, we wondered why we had balked at the pricetag.  These things work, plain and simple.  No slipping on ice, easy on and off, stability on the trail beyond belief.
If you do any outdoor winter activities, BUY these!  You will love them.  I now keep them in my backpack all winter long, just in case I run into icy patches on my hikes.
