I just got Nathan's from the sale which are the fifth aves. I saw online somewhere that they thought the ja bank versions were made on different lasts. The fifth on 7 and the park on 8 instead of the 5 last. After receiving my shoes I think they are right. Quality is the same. The 7 seems to fit me better anyway
Do you mind providing more details on the Jos A Bank versions you got? I have always liked the idea of getting these shoes on those lasts, but haven't ever had a chance to see them in person. None of the Jos A Bank stores near me carry them in the shop. Do you mind saying how much they were, and posting photos?
