Murray: I don't know how you'll duplicate this in Munich, but there's a wonderful running shoe store here in Albuquerque, Heart and Sole (sorry, ignore the pun) that offers a good solution to your problem. They've got a treadmill in store with a video camera at foot level. The guy talks to you, guesses about a pair of shoes that might address your biomechanical issues, then has you run while he videotapes your foot fall. Then he plays it back, freeze-framing and stepping slowly through your entire stride to figure out if the shoe is addressing your problem. (And we all have problems.)

It resulted in the best running shoe fit I've ever had. Obviously, a plane ticket to Albuquerque is probably out of the question, but there must be someone in a great city like Munich that's doing this.
