Replying to Switch from 99mm boot to 102mm boot - Am I fucked?

I just bought a new pair of Full Tilt B&Es s to replace my rusty old ones and noticed they changed the with to 102. While I was a little tight in my 99s, I feel comfortable in my 102s. My issue is that my fucking heal keeps trying to pop out of the boot, with the liner. It seems my heel just wants out and the liner just seems to slip along the shell with no resistance. Has anyone else experienced this with Full Tilts? Should I ditch this pair and cop a pair of 99mm boots asap? Any help would be muuuuuch appreciated. thanks guys.
