The answer to your question is in your EDITED portion of this message!!! You tried the shoes on, but you did not have him walk around in them!!! And whoever sold you those shoes, didn't know what they were doing. My grandma (God rest her soul) always told me to try the shoes on, and walk around in them like you would normally walk - not as if you are trying on a pair of shoes. I really hope this helps, and good luck!!
