I'm pretty happy with mine. The roads around here are mainly dirt tracks, so even if the snow has melted in places I'm walking on soft earth. The only paved road gets cleared after heavy snow, but there is hardly any traffic. It generally has at least an inch of ice and snow on it. I can see how walking on dry roads would be a problem, like wearing 8 pairs of stilettos at once!
Yes, they're pretty much like the YakTrax. They criss-cross under the shoe. They really bite into snow and ice. Do you like yours? Do yours work well, too?
The only problem I can find is that they usually only last one season. Part of the problem is that you're not supposed to wear them on dry roads; they're really meant for snow and ice. The problem is that (and I mentioned this before) not all property owners clean their sidewalks and as passersby walk in the snow, they wear it down and it eventually turns into an icy mess. I am scared to death of falling (I have osteopenia and my doctor always says, "Whatever you do, don't fall!). So I wear the YakTrax until I know that sidewalks are clear, the sides of the roads are OK, etc. So part of the time, I walk on ice and snow; the other part I'm on dry roads. And the coils aren't made for dryness....and they will break/snap. I usually end up buying a new pair at the beginning of the winter season. Still, I suppose it's cheaper than falling down and breaking a bone.
2.25 miles on the treadmill this morning.
An hour of yoga today.
