For those boots with non-leather soles, most of mine have previously been commando. I recently acquired a couple pairs with Dainite soles and I have been quite impressed. Definitely prefer the silhouette of them to a commando sole, although I guess I could see how the commando would theoretically provide more traction.
We don't get much snow in El Paso.
In the real bad stuff, you'll get some snow that fills in the studs, and that wouldn't really happen with commando soles, but I haven't found it to be an issue for me. Ice is where traction is really lacking, and every sole will have a rough time on that.
