Hard to tell just looking at pictures, and I'm not a expert at determining whether smething is fake as I don't know the exact details to look out for. But to me it looks okay. If you don't mind me asking where the boots are being sold from? (Ebay etc..) If the price is much lower than usual and the seller has at least a 99% positive rating than it may be O.K.
I really like the Dior homme sneakers and boots but the price puts me off, maybe one day
