At that time ignorant of midsole yellowing of even midsole cracking and separating midsoles, I bought them because a) they looked fantastic and b) back in the days these were quasi unaffordable, with a price tag of over 150 euro’s (an that was in 1991 a LOT OF MONEY!)
Damage after all that use: not a lot. I think these are in fact one of the few wearable pairs left. Midsoles are in very good shape, some minor glue drying, but in general: excellent condition!
I have to say, after all these years, these look still very hot!
