It's hard to say whether these are legit or not because of how beat they are, also the potato pictures you received didn't help. You need a picture from under the waffle tab to be sure, but so far they don't have any alarming signs.
If you look at the soles of the shoes, they have been worn unevenly, which can account for the perceived different heights in the photos. It also depends how the pictures were taken, plus these shoes are pretty beat.
