O.k. I can fit junior pulsions but i cant seem to fit total 90 3s because they are to wide. So do you think i can fit nike vapors fine if they are laced as tight as possible. Also some people say nikes are sized different than adidas. (like an adidas 6 is a 6.5 in nike so nikes are sized bigger. I am small so i wear a junior and since i am small i have narrow foot. I might be getting a vapor 5.5 since i wear a adidas 5.
