Replying to Ridiculous foot cramp

I get the must ridiculous foot crap on the side of my feet near my arches, which means i have to stop every 15 mins or after a run to massage my feet. It does go away after a few hours, but still hurts to ski and it is really pissing me off. I also have a massive instep like nothing you have ever seen. I have salmon quests boots which are fitted properly and i have custom insoles. I went for one week with my new boots and still had problems so took them to some fag smoking striped shirt french foot man in tignes who did all kinds of things to the boots, it was alright for one day then it all came back again. So i took them back to snow and rock to be reheated and fitted. Went away for another week and the same problem still. So i took them back again to someone who new what they was talking about well as it seemed. The guy said because of my high instep and the blood vessels on the top of your feet with pressure on this part can cut of circulation, so he took like 2mm off the boot insole and some plastic crap bit i didn't need on the custom insole and told me to wear fin socks with just padding on the key areas. I haven't yet had a chance to test em out, hopefully i will be soon up in hemel.
