I wasn't sure where to post this because I feel like it could be either a boot issue, a technique issue, a fitness issue, or any combination of the above.
I got back into skiing last year after taking about 10 years off and the gear and technique have changed a lot. One thing that hasn't changed is the deep, sometimes crippling (hyperbole) soreness or fatigue that develops in my feet while skiing, especially when I ski bumps or more technical terrain (trees) that require a different technique than the groomers I ski 90% of the time. The pain seems to originate on outer front part of the underside of the foot, where the arch meets the ball underneath the smallest toes. Prior to my hiatus I skied mainly on smaller hills in Michigan and don't recall noticing the problem except during my annual trips out west, and then mainly when I skied bumps.
Now back in the game, skiing on the East Coast (mainly Hunter, with one recent trip to Stowe), I've been experiencing the same pain, but it has been affecting me earlier in the day and on less technical terrain (e.g. after skiing groomers). The pain will mainly disappear while on the lift (when I unbuckle my boots). As before, the pain is worse when skiing bumps, and seems to vary with the degree of difficulty. For example, at Stowe this past weekend the pain was manageable while skiing liftline, unbearable while skiing Goat, and pretty much non existent while skiing a shorter blue bump run with relatively even bumps (forgot the name). I've skied 7 days this year and the first time I didn't feel the pain was the last day I skied at Stowe this past Sunday.
So, due to the nature of the pain I've decided that it is probably caused either by some technique issue or just due to a lack of fitness, but I haven't ruled out a boot or biomechanical issue. Another potentially useful piece of information is that I've experienced the same pain recently doing the jumping drills on the Insanity workout DVDs.
If anybody has an idea what might be causing this pain / fatigue and has any recommendations to fix it, I will really appreciate it.
