How does the fitting run for LV sneakers?

I am usually a 7.5 for Adidas sneakers such as the Ultraboost but I know designer shoes tend to run big. I need to size down to US 6 for Alexander McQueen sneakers and the Balenciaga trainer.

Does it go the same for LV? Or would it be true to size? Or if the oversizing is not that significant compared to Balenciaga or Mcqueen.
