I know this is old, but just adding to this, as I didnt see anyone mention it, and it may help other people legit checking: the print is wrong.
If you were looking at the shoes as if you had them on, the LEFT panel of both shoes should match (approximately) and the RIGHT panel of both shoes should match (approximately) as well. Unlike most shoes, where the medial and lateral sides would match. Here that doesn't matter. Legit pairs have matching left and matching right panels.
You can see what I'm talking about using my pair as an example:
JPS, the yeezys you posted had matching medial ("inside") and lateral ("outside") panels, with the pattern on both shoes flowing OUTWARDS towards each respective foot's pinky toe.
This is a DEAD giveaway when it comes to most fakes, however from what I've seen, it appears that updated 350 fakes are on the horizon, if not already available for purchase, that apparently FIX this issue.
So this may help now, but a word of warning, who knows in a few weeks/months after these "new" fakes have flooded in.
Also, I think it's worth noting: THE 350 COMPARISON VIDEO IN THE OP NEEDS TO BE REMOVED. That video is comparing a "replica" pair of 350s with an "unauthorized authentic" pair of 350s, which is just a label being used to distinguish it as a higher grade of replica. That video doesn't help anyone!
