Gucci ace trainers - sizing

[countrygirl171]

I've seen some second hand Gucci ace trainers for sale but I was just wondering about the sizing... Do they tend to come up big or are they pretty true to size? Thank you.

They come up slightly big imo. I ordered half a size down

Ok, thank you.

They are huge. I went over a size down and they are still too big

So if my Vejas are a 40 and Chloe Susanna boots are a 40, would you go down to a 39? Thank you.
