I received this as a gift many years ago (probably somewhere around 2018/2019). I don’t have any documents with them nor their box since I’ve moved a few times since. Size is Euro 40. Not fully sure of the authentici7y since I wasn’t the one that bought them, but they are very sturdy, even though I wore them a bit they still have so much life in them and if anything the boots have proven themselves worthy. Hence why I don’t have any docs for them why is the price. You are getting exactly what is pictured.
