I would try and transition slowly to Altra if the heel-to-toe offset really is as little as I’m thinking. Start with very short runs and work on calf strengthening. You might be able to get insoles which allow a more forgiving drop and so don’t kill your achilles/calves
I do not know, it's due to the width that the chap recommended them.
That said, I find my current Adidas really comfortable, but will probably try some Altra next.
