look legit to me and a reseller price isn't much if your paying retail than you could probably make about 50$ but they would be hard to sell because of the price.
not a huge expert but I'm pretty sure there fake just cause of the price. these are very expensive sneakers and I've seen some more beat than these go for more
the strap is faded i don't really know what to do there but on the heel I'm pretty sure they have glue made for that but if not i would use super glue because i and a pair of lebron 10 elite sport turq and the carbon fiber on the side was ripped and i used super glue and you could never tell it...
