The Zipper doesn't allow easy on/off - you have to unlace the shoes as well, which defeats the purpose of having the zipper. I bought them hoping they would have exceptionally great traction on ice, but they're just mediocre.  They're not even very warm so I have to wear really thick socks. The footbed is removable if you use an orthotic insert. Basically, these boots are just okay.  I prefer insulated timberlands (with "grip stick" soles) to these.
