"The sizes are European. I ordered this boot in size 11, and I was sent a 41! 41 is a size 9 in Europe, not size 11. I would need a 43, and that's clearly not what I got. I'm really bummed, it's super cute. But they don't make it in 43. If you have smaller feet, order at least a size up (maybe two) and this should work for you."
