Why is "safety" footwear necessary? I switched from boots to trail runners 9 years ago, and have never worn boots since.

if you are climbing rather than hiking, you may need specialized footwear, but that is not industrial "safety" footwear.

Another word of warning--shoe fit is an extremely individual matter--everyone's feet are different and shoe sizes/lasts are not standard. "Surprising" someone with a gift of shoes is the worst possible thing you can do. It guarantees that she'll have very painful feet--and blame you for it! (I would!) If you want to do this as a gift, please give her the money or a gift certificate and let her purchase her own!
