There’s nothing worse than riding in an ill-fitting pair of boots- trust me, I once got the wrong size, (the lady working only gave me two pairs to try on... it was a mess honestly lol) and I got terrible blisters and cuts on my ankles from it. If you think your feet are still going to grow, I would wait to get tall boots, or just get a cheap pair for the time being and then in a year or so you can see how they fit and determine whether you need to get a different size.
Why not get a cheaper pair until you are sure you've finished growing?
I would get the ones that fit well now, it’s not nice to ride in boots that don’t fit well (take it from someone who did exactly this and never actually grew in to them), and if you keep them in good condition you can always resell them once/if they don’t fit anymore!
I'm in the process of getting tall boots. I've tried sizes 7 and 7.5. The calf and the ankle of the 7 fit better...
But I'm afraid that my foot will get bigger ( I'm 14 so I don't know if my foot will get any bigger...?) and will no longer fit in the 7. So I tried the 7.5, so they could be worn longer for if my foot gets bigger. But, the calf and the ankles of them don't fit as well as the 7s, so which one should I choose? Also, I can't just wear these boots for like only a year since they are quite expensive and I don't want to spend more money on another pair.
So which pair should I choose? The pair that fits perfect now, or the ones that will still fit me if I grow...?
