I have been mis-fitted at John Lobb, Crocket & Jones and several of the top-tier department stores. And yes, at Allen Edmonds too.
My experience is that when you are fitted,
- 45% of the time, the person helping you does not know how to tell if you have a good fit
- 45% of the time, the person helping you assumes that you want to judge yourself by walking for a few steps
- 10% of the time, the person actually knows how to fit you and proactively does so
So, my advice...
