Do you have some boot recommendations or reviews you’d recommend?
Honestly not sure of the best recommendations these days. And depends if you go above treeline and/or do winter backpacks.
For zero C (32 F), there are a lot of boots that are fine for day hikes. The main limitation of something like microspikes vs. full crampons is that they only work well up to a certain angle at which point they don't really work for hard ice.
You can't really go wrong with Sorels especially for non-high angle hiking. I've actually been an instructor in winter hiking programs.
