They look legit to me. The toe box has the correct shapes and the 23 is the right size unlike the smaller size seen on fakes, but your kicks look legit dude!
If you got the 72-10's to try and resell them then do the trade because the 72-10's resell value is going to be below retail in a couple weeks time. The Air Max 1 "The 6" were a Toronto Exclusive release that really didn't catch that much hype so I would keep the 72-10's if your just getting...
To be honest with you the toebox is kinda sketchy and the 23 on the back heel is small compared to most pairs. I'm leaning towards fakes. Gotta do your research before buying shoes these days. Good Luck:)
Unlikely, but you can always try to contact the seller and ask. Sorry bro you just gotta be careful and do a lot of research when buying shoes these days. Good Luck :)
