Long time lurker, first time poster ,before I get the customary " go see your bootfitter" - I already did and spent considerable money on this. I am 5'10 200 lbs. I was having right foot arch pain, that was pretty severe. The bootfitter said my boots were one size too big and recommended I buy the Head Adaptedge 100. I did. In many ways the Arch pain got worse, despite them feeling amazing in the shop. So next thing I always read is custom footbeds. Now I will admit these were not from a ski shop, they were from an Orthotics company that happens to have a ski insert. They cost 475.00 for them but insurance covered most. These were made using a pressure mat and a GAIT scan. I wore them for two weeks in shoes to "break them in" then put them in ski boots when it came time to put pressure down on those babies, my arches hurt so bad to the point I could no longer ski -- The first run was amazing because of how they were molded but after that they hurt like all hell. I removed them at the top of the mountain in blowing snow. (Thats how bad they hurt). So Alas, I removed EVERYTHING no footbeds whatsoever, just ski'd on flat liner of the adaptedge. The arch pain went away - but now I could feel every bump and lump in the snow. I then thought I needed some "shock absorption" I got some off the shelf gel insoles and ripped off the plastic arch supports and cut them to the size of my insoles. This worked the best of everything I tried, but I still feel like I am giving up that "snug fit" in exchange for tolerability.
My personal thoughts are now to just get a perfectly flat gel insole to go inside ( with zero arch supports), but I would love to hear anyone's thoughts. Lou If your reading this, I may be down in Calgary April 20th'ish Will you be around? thinking of maybe stopping in..
