i think ysl's are shit to be honest. most used pairs that i've see for sale have cracks on the soles, toes, and just look like they'll fall apart easily after being worn. I don't think the construction is very good, they just don't hold up well over time. soles are not even stitched which is kind of unacceptable at that price range, and on the bottom, they have those chuck taylor styled soles that look like it will come off easily. i've seen cp's and other sneakers that look far better after years of wear than ysl's. your pair doesn't look that bad though, much better than other pairs i've seen. i'd only get them if they're cheap.
