Shoes are a bit tight (tighter than other Adidas) but I returned because the tongues were different. Maybe it's relevant now, but I've never seen tongues on each shoe being different. Especially when you consider that it is just a QR code. It may not matter much to most, but I'm not a fan. Or, since the ad doesn't show a picture of the right boot's tongue, it could be a defect. I am not sure. See pictures.
