Over the past few years, I have frequently visited, googled, and searched boarding forums to relieve foot pain. The problem is, it gets sooo bad I have to take 10-15 minute rests at times, or a major pain killer to enjoy boarding. Here are the symptoms and things I've tried to get rid of the problem.
I'm fine at first, longer runs and I start getting excruciating pain near the arches/middle of my feet. It basically feels like both of my feet are going through a major foot cramp, even though they aren't.
Different pairs, sizes, etc: 1 Soloman, 2 pairs of K2s, baked the inner lining, tried wearing looser, tried making the lining looser, wearing them a bit tighter, etc.
Shitty 1st board bindings, to Flows, to Ride SPIs and Ride Alpha Movement. No major difference in Bindings. I've adjusted front and rear angles and backings (front rear from +/- 25 to 15/0, no relief) and (backings up to 45%, no relief).
Arbor Mystic, Ride DH.
I've tried both Surefeet and $250 custom inserts, neither of which have helped.
I'm starting to think the boots are my problem, but if anyone has had something similar to where they seriously sometimes had to sit down during a run and stop for a bit because their feet were hurting so much that would help. Another thing I've noticed is terrain that requires a lot of turns or navigating causes me the biggest foot problems (moguls, tree runs, etc).
Evidently in your searches you've never found a forum where I've answered this question numerous times.
What's going on is you're flat footed and don't have metatarsal arch support, you have traditional arch support. So when you start riding the arch is collapsing and that's where the pain is coming from.
Any time a specialist recommends Surefoot (or as we call it Sore Foot) they should be pimp slapped. They have the name, they've been around forever, but they don't make a solid product. Go see a ski boot specialist, find one that has been doing it for at least 10 years. Find someone that's going to build the footbed from the ground up. Be prepared for multiple visits to see them.
I'm also going to suggest that the boots are probably a hair too big and your foot is sliding forward a bit, this can cause that problem as well. Riding with the boot loose is only adding to the problem. You need the boot to be snug, if it's loose your foot is just sliding around in there again.
The other thing can be where the internal harness sits on the foot.
