I've had custom footbeds made and the liners heat molded. I'm in the 21.5 Dalbello Kryzma w the intuition liner. I think the flex is OK.
I skied yesterday for three or four hours in spring conditions.
I thought I might not get through the first run. I took the boot off, checked the footbed placement to o be sure it was correctly seated, and took some more runs. i had to unbuckle the buckles on the lift. There was alot of pressure in the toe area, on both size of the widest parts of my forefoot. There was also pressure coming down over the forefoot, and some pressure coming up from the footbed, only on the right foot, under my arch. I would never be able to tolerate these for a whole day and certainly not in colder temps.
They got somewhat better as the hours wore on, but not enough to want to try them again before getting them adjusted/giving up the ghost. I did, however, very much like the performance. They gave me great snow feel and were very quick to respond. Much better than the Tecnica 90 Attiva (21.5) I am currently in.
I'd like to make them work but wonder if I should keep trying. My heel is very narrow but I have a normal forefoot. I measure a true 21.5. 100#, 5', advanced.
Open to all suggestions. I liked these boots for the progressive flex and more upright stance as well.
