Adidas Gazelle sizing?

[MadameSapphire]

Just that, really! Looking to get some of the flatform ones and haven’t had Adidas in years. I’m a 4.5 in Nikes and 4 in Superga. Thank you.

I am a 7 in Nikes and I purchased gazelles in a 7. They fit but because they feel flatter and less cushioned I think I would buy a 7.5 next time. But not much difference to be fair.

I'm a 3.5, though occasionally a 4.
Went with 3.5 but find them tight and wish I'd gone for a 4!
