Based on the google images I am seeing for altan bottier, you are asking about a type of shoe that doesn't get much pub on styleforum. I have yet to see someone of the WAYWRN club to post green or bright purple shoes.
Maybe because the pants look a little baggy it makes the jacket look like it doesn't cover your arse. With this size 46 there looks to be a lot of excess fabric movement all over. You may want to try the same size in a Lazio.
