It sounds as if the ski boots and inline skates do not have enough volume
in the instep area to fit your feet correctly. I would not go with the footbed
route at this point, unless you will be installing one that is thinner than the one that is in the boot or skate already. If you have a footbed fabricated, I would not necessarily go with a cork model as it does not offer the shock absorption that your foot probably needs. Make sure it is made with a good shock absorbing material (ie.. EVA foam). Next, make sure that the liners have enough volume at the instep area for your feet. If they don't, have them altered by a competant bootfitter. Also, if needed, have the bootboards lowered to allow for more room on the instep area. Last but not least, have the instep buckles moved to a more favorable position. As a note, there are more things that can be done to help, but time does not allow to go into detail. Any questions, email me.
