Just got Nike Flight Five OGs for $129

I just won Nike Flight Five OGs on eBay for $129! They are size 8.5 and I normally wear 9.5 but I had got the retro flight fives in cool grey several years ago and they fit almost a full size too big so I'm hoping the OGs run big like the retroes did, does anyone know?

In any case I think that's an awesome price for OG Flight Fives!

Thanks
