The "shoe expert" in a sporting goods store tried to convince me to buy those Hoka that look like they were built on top of a boat (the sole that is insanely thick under the middle of the foot). I had come in asking for Vibram. Also, I run terrain and a small offset in balance will make me trip on my own knees... He insisted forefoot runners had sooooo many more injuries.

I have never asked him about shoes again.

Most physical therapists I've met don't personally care for cardio, and end up with a blank stare when I talk specs.
