Nike SF AF1 Quality?

I bought two pairs of the Special Field Air Force 1s. I got one pair directly from Nike, and another overseas from Sneakersnstuff.
The leather quality on each pair is completely different from each other. The pair from Nike is more of a grainy pebbled leather, while the SNS pair is a much smoother leather.

Each box has a stamp, the one from Nike has a F/23 stamp for whatever reason. Why is this? Wtf does it mean lol


Not sure where to post this, sorry mods, feel free to move it or whatever. Not sure if this is important or if I'm over analyzing but I just thought it was strange and maybe someone might have an explanation for it haha.

not all leather is the same, don't worry lol. They will all age and be unique with time.

What size are they? DM me if you're interested in selling.

I'll buy a 12 or 12.5 if interested in selling dm
