hi,
My feets are horrible, and I did struggle a lot with my ski boots, very painfull. I tried a place in Geneva, and they sold me very large boot, they promise a good fit, but it did not work, even after many tries. Still painful, and poor control because the boot was huge.
Then I went to Chamonix, In my opinion places there are at a different level. I had to get new boots because apparently there is now solution if your boots are too big. They sold me much smaller boots, and fit them propoperly. Now I sky pain free.
Sole and Footworks are both very good. As far as I know the staff from Sole are former Footworks.
