For the record, that's exactly how the OG's did fit back in 1992, as well as some early retros such as the firsts French Blues and Olympics from what I can remember.
Some 7 retros, namely '11 Bordeaux, Cardinals and '12 Playoffs were looser to the point where I've had 7's slip out completely on more than a few occasions on court when exploding to the basket. Never lost any other shoes on court besides the 7's.
My '14 Hares are closer to the originals as far as fit is concerned. I cannot speak for the ones that were issued after since I haven't got any because of what I just explained.
With that being said, what you've just described, to me it's a good thing!
