Why cant you return them? Everytime ive had an issue with stockx i emailed them and they got back to me within the next day and offered a refund or $25 off.
I cant even tell that they arent as shiny as the navys, they both look the same too me. Only diffrences ive noticed is the tumbled leather and stiff tongue tag.
I got a pair a few months ago they are fine, no paint chipping or crumbling. Paint will eventually chip on these, but that personally doesnt bother me, so thats up to you.
