Those were also in a horrible condition. These are looking pretty good for a trainer manufactured in 1991. The plastic has not cracked too much although there are a few cracks here and there. They are a black/purple colour with a leather/nubuck type upper and some sort of plastic/rubber sole.I did want to clean them up but had fears that I may end up doing something I would regret.
