I am not much help on guys shoes. To me they all kinda look the same. Some guys say the same about my girly shoes. Anyways, there is a site about sneakers. THOSE guys can tell you about the history of specific shoes. They are a crack up. So go to
Nice Kicks and see if they can help.
These shoes aren't exactly like what you have, but look at them because they might work as alternatives.
