With the vegan leather that Adidas used on the Orchard Sambas and black/black Superstars from a couple years ago, there was a visible grain but it couldn’t be seen in photos. I agree that there are vegan leathers where the grain is visible even in photos, but those are usually used in more expensive items like loafers made with grape leather. I doubt Adidas would use vegan leather, especially the better stuff, without increasing the price.
If no one confirms before Wednesday, I can confirm what’s on the materials tag since I’ll be in a different city where the skate shop has the Pros in stock.
