Replying to Dalbello boss toe bang

alright so this year I upgraded from shitty rossi exhalt boots to dalbello boss's. I love the flex and feel and everything except im getting some gnarly toe bang  (fully black and blue big toes for over a week).  I used to wear size 29.5 but these r 28.5 and I have way more control that way and my toes dont hit except on hard landings.  this is a 3 piece boot so i try and get the ankle buckle super tight but it doesnt work. and please dont say jus land beeter serious responses only please. will just punching out the toe box at the shop cure this or is there something else i should do?
