I asked a related question over in the bootfitter section but I'm interested in getting some feedback from the skiing community as a whole. I'm looking to buy some ZipFit liners for my Head Raptor RS 115 boots, to replace the original liners which have packed out rather now. The Raptors have a narrowish fit (98mm) last, but I have VERY skinny feet and shins, so that now I am skiing with the boots buckled up to the last available notch. Shell fit is verging on 'comfort' (17mm), but I'm not really in a position to go down a size with the shells and have the necessary work done to make them fit, so I'm looking for ZipFits to restore the original snug feel.
I suspect that the Grand Prix model is probably what I'm ideally after. But I'm not sure I can get hold of them in the right size. I can probably get hold of some Classics, though. Would they be too thick for the Raptor boots, though?
