I'm not sure Sorels are as good as they used to be. But, yeah, for not super steep hiking they're great (you can't really front point). And you can even carry an extra pair of liners for backpacking. For flat these days, they're great for microspikes. When I was getting started in winter hiking, it's what most people used. I only got plastics when I started doing some real mountaineering.
You can't really go wrong with Sorels especially for non-high angle hiking. I've actually been an instructor in winter hiking programs.
