Replying to Boot help....advice welcome.

howdy,
my GF is looking for new boots she currently uses Salomon X wave 8s which pretty much cripple her whenever we ski so they need to be destroyed. We went round every ski shop in courchevel and meribel at the end of 05 season and tried pretty much everything on with no real stand out success. She has a really high instep, average with toes and skinny heels and cos she is a femme has low calf muscles(eg the top of the boot needs to be wide-ish) from the looks of it the technica attiva seems to be the one to try on paper but if anyone has similar feet or knowledge let me know what to give a shot. much appreciated. taa
