Bests & Worsts Reviews from Amazon

I didn't realize until after I had already decorated these shoes as a gift, and so cannot return them, but they aren't even the same shoe! They look the same at first glance, and are the same size, but one shoe has 7 eyelets, the other has 8. They also came with one long and one short lace. While this is pretty minor visually, it begs the question: Are these even authentic Converse? How could a legitimate company make such a mistake?
