I bought a pair of Head Raptor Project RS 115 boots a couple of years ago, which I found to be absolutely excellent. I spent a long time beforehand trying to persuade myself that I could squeeze into a 26.5 size, for a performance fit, but I came to the conclusion that the only way they could be made wearable at all for me would be after extensive work by a bootfitter, preferably in-resort so I could go back there to deal with teething troubles. Being based in Britain and flying to the Alps for ski holidays, this wasn't really viable for me. So I went for 27.5 (the liner actually says 27.0 on it, and the shells themselves have no size marking other than for length, 313mm). These felt pretty snug and have worked out well.
Now, though, 2 years later, the liners have clearly packed out somewhat, and by mid-morning I need to tighten the boots up to the last notch on the buckles. By mid afternoon, they're starting to feel a little loose and I don't feel that immediate communication with my skis that I'm looking for. So I need to find some solution. One of my main problems is that I have very skinny feet and thin calves, so most boots are rather too voluminous for me. The Raptors are a 98mm last, though, which is one of the reasons I chose them.
So, I'm thinking of getting some ZipFit liners. Problem is that nowhere local to me sells them so I either have to travel a long way to get them, which I don't really have time to do just now, or buy them online. I'm not sure which ones I would need, though. Maybe Grand Prix? I would ideally like them to take up just a little more volume than the original liners. I really like the prospect of extremely good heel hold and an overall tight fit which doesn't pack out. Unfortunately ZipFits are not widely available in the UK, although CEM on here does them, I know, and I would go to see him if I could find the time.
So any suggestions on model and sizing would be most welcome!
