Air bubble looks somewhat tinted. There's a bit wrong with these, I'd say they aren't legit. If you paid using a PP invoice, you can go to create and manage invoices I believe and go from there.
Gee, the tongue stitching though.. These look alright however. Purchase like @TIMMYBRIXXX said, PayPal invoice and 100% authentic in order to be liable to get a refund if they are fake.
These seem a little sketchy.. To me, the cuts of the shoe seem pretty sloppy and the tongues seem a little too puffy IMO.. It may just be me though. I'd wait for more opinions.
