Full tilt Hot Dogger boots heal chipping a little

So guys recently I got a pair of Full Tilt Hot Dogger boots. The 2012 ones. I got them for $80 from a friend so I mean they weren't mint condition and they had a bottom buckle replaced, but anyway the heals are chipping a little and I'm wondering if this is because my boot is smushed against the back binding of my marker griffons and when I put my boot in it gets chipped. Im not sure about this though. Help me out NS. I pushed the bindings a little closer to the boot because the boot would "jiggle" very little and it wouldn't affect me at all. The rear heals of the boot are definitely worn to shit, so I am going to order new heals for the boot which is only $20. BTW my bindings are brand new so would me getting a new heal piece on both boots solve me problem and to I need to move the bindings back a bit and just turn up the din? Thanks for any feedback!
