Take away the electric heating feature in these boots and these are great all by themselves.  While the heaters are an enticing feature your better off leaving them out of the equation.  Like most of the other posters the heating ability fades rather quickly, to the point that I can't tell if they're heating at all.

I have yet to have an issue with traction, warmth, or wetness from these boots.  They fit snug and provide a sturdy grip on icy surfaces.  Please don't take that to mean you can go running on ice and not fall.  I mean compared to everyday shoes these have extremely better traction and will help keep you from busting your cushion or breaking bones from and unexpected fall.

Overall these are my go to boots in the winter months while snow is on the ground.  They come up to about mid shin to provide resistance to snow and ice melt.  I have never had an issue with warmth or traction.  Personally I think they should drop the price and sell these without the battery packs or heating feature and I would be much more impressed with them.  as I've seen in the other posts the heating feature isn't lasting.
