Our Legacy Camion Boots Size 45

Size EU 45 (US 11-12) fits like size 11-12 in runners, I am slightly above size 12 so it is a bit tight for me. Black leather boots from Our Legacy. These Camion boots are size 45 and have a square toe design. The soles are Vibram rubber for durability. A side zipper closure is on the inner ankle of each boot. Brand new comes with box and everything, only tried on, received as gifts but they are tiny bit too small. Willing to exchange for size 46 as well.
