Replying to I have skinny calfs an i think the tops of my boots are too loose

So Yes i went to a boot fitter, yes i got fitted into a wide boot with a high instep. ended up with the descendant 8 after being fitted at 4 different shops. Yes i got them punched even more to fit my feet better. They fit great now. Only problem is i think i have fairly skinny calves and when i try to butter or press i get shin pain especially on tail butters. Theres a bit of travel in my upper calf right where the boot ends. Should this space be filled and my upper calf shouldnt have that much range? i keep my boots really tight already
