im getting the cardinal and orion Jordan 7 but they are size 12 in men so in the future will I eventually fit in them and about how many inches or cm. bigger will it be

I wore 11s when I was your age, and I only got up to 11.5. I do have one pair of 12s, but most 12s are just a little too big. I suggest looking for 11s or 11.5s.
