There's a lot of difference between a hiking boot and a ski boot! The ski boot is basically like a cast, and i've never seen a hiking boot like that.

I didn't believe it either until I tried trail runners, forced by not being able to find women's boots without Goretex lining. My daughter was really skeptical! However, I have not turned an ankle a single time since I made the switch to trail runners 10 years ago, while I was constantly turning my ankles in the hiking boots!
