Replying to Full tilt Problem

Hi all, so here is the sitch. I recently went into Evo and got fitted for new boots. We went through a lot of boots with thin lasts and the only boot that fit me were some FullTilt first chairs. They were a little expensive and out of my price range so I bought some 16' Tom Wallisch boots since they have the same Soul shell. The feet fit great length wise and width wise, the only problem I had was there was space above my foot. So I went in to Evo and they put in 2mm of these spacers in and they did the job. My problem I have that I'm asking you guys about is the heel fit and calf fit. I have the middle and top cables as tight as they can go and I have a good 5mm of up and down movement when trying to lift my heal in the boot. also in the upper portion of the boot I have the strap and the cable as tight as possible and I can fit about two pencil widths down in the boot.

Do you guys think I should buy smaller boots or buy shorter cables?

Also I know I gave a lot of info and this is a pretty noob question and I appreciate any help given.
