I currently have "original" Nike Cortez's from 1979. Not store bought, these have been in possession for a while. THey are like new, were worn perhaps once, but that was it. The sole and everything remains intact. If interested I'd be more than happy to send pics. The shoes are a size 9' and to give an idea of what shoe I'm talking about, Seb Coe can be seen running with them in the video Born to Run.
I will not trade for these unless you have something of equal trade.
