I used to wear Army boots all the time because they were issued to me and were free. I loved them. Quick in lacing, waterproof but on the snow or wet surfaces they were worst than ice skates. But one got used to it. Than for one trek I got Scarpa backpacking boots. Now it was a totally different concept. They were warmer (more problematic in the summer), more expensive, not as high and heavier. I wear them now and swer by them the same way I sweared by Army boots. Since I work as an EMT I go between hiking boots and Army boots. I really hate changing like that since my feet can't really get used to either shape. In the end you have to try out what's good for you.

Here are some boots I used in the past:
