Replying to Full Tilt help

Hey I got finally a change to try out the new Drop Kicks and Hot Doggers and I found nasty pressure point from Drop Kicks even tho they are almost the same as Doggers so here I begin: Well I tried that 28.5 size dogger and 27.5 drop kicks. And I found 27.5 to be to small I know they will mold but they were still to small from length so I wonder if I should go with 28 boots since 28.5 felt perfect but doesn't the liner pack out a bit after few days? So that's why I am asking from you, should I go with 28.5 and hope for the best or 28.0 I didn't have the change to try that size so which one? And isn't the shell 28.5 and liner 28.0 size in that ''28.0'' Dogger so thats why the liner will pack out? They felt better than any boot before so sure I am going to buy them but half size up or not? ARRR!!!!???
