The problem with Altra is that they are so completely different from other shoes. I have tried them and I couldn´t run in them. The low drop killed my achilles and the ridiculously wide toebox felt very akward when I was trying to run fast. I guess she must have tried them and liked them. You just don´t switch to Altra for the money.
If the low drop hurts you, you have really been hurt by the high drop for years previously. Ditto with foot shaped toe box. Just need to give it more time and you'll never switch back.
As an Altra fan, I just hope she understands and embraces what makes Altra special and doesn't do it for a while and then go back to high heeled, toe squashing shoes for a bigger buck.
