At the end of the season last year I got myself some Head S8 boots, but ended up not doing any skiing in them until this season. I've just come back from a week's ski trip and am impressed with the boots - but I found I have a bit of a problem. At the beginning of the day, if I tighten the buckles enough so the boots are really snug (allowing me to get the ski from edge to edge quickly), I often get an agonising cramp or spasm in the arches of my feet. If I do a few runs with the boots loose, and then gradually tighten them up over the course of the day, I manage to avoid this, but it's a bit of a nuisance (particularly if there is some nice powder first thing which is likely to get tracked out soon).
Has anyone got a good idea about what causes this kind of cramp and how it can be avoided?
I have rather narrow feet but the boots have Head's Full Custom System, meaning that a plastic insert narrows the 103mm width down somewhat. I did the full shell test, etc., in the shop and they were (as far as I could tell) the correct size. I am still using custom footbeds made some years ago - I haven't yet had a chance to get some made by a Harb-qualified person, although I'd love to. Do you think better footbeds might alleviate the problem? (I get the problem with the stock inserts, though, so it doesn't seem to be specific to my current footbeds).
