I say ---- go in to the running store with a friend---to take some of the awkwardness off----I'm sure the wife will be more interested in selling shoes than whatever happened between her hubby and your son.
I went to one of those stores to get the right shoe when I walked The 3 Day. It was well worth the stop! So good to read of your progress!
