Tall fracture boot vs Short fracture boot, which is better for runners?

It's no secret that I truly believe fracture walking boots are overprescribed, overused and used for way too long for many injured runners with many different kinds of overtraining injuries. But sometimes I recommend runners use a fracture walking boot for a short period of time. Then teh question becomes which kind? Short boot or Tall boot? A tall fracture walking boot versus a short fracture walking boot. Which one is better if you're an injured runner?  Well, that's what we're talking about today on the Doc On The Run Podcast.
