So I'm going to buy some Gucci shoes online but I have no idea what size to get. US and European sizes are completely different, I have a Gucci belt and the size is completely different than what I was trying to get. Also, I asked a couple of people and they said go a size down so since I'm a size 12.5, I was told to buy a size 11 or 11.5. Also, one person also told me to even possibly go down two sizes. So I'm just really confused, any help would be appreciated.
Here's the pair im talking about.
