Planning to buy Balenciaga 3XL

Hi guys, want your consultation. Thank you in advance.

Planning to buy 3XLs and im not sure about size.

I have track sneakers and to my dissapointment i took the size acording to centimetres - my foot is 27cm so belenciaga track is 41 in EU size. The thing is that they are quite snug.

I want to buy 3XLs now and dont know what size to choose because official balenciaga website says they run larger. So maybe i should take size 41 - 27cm or choose size 42 - 27,5cm? Thank you for your oppinions.
