I swear I've had this issue since my first pair of properly fitted boots.
I'm now on a pair of Dalbello Panterra 120's, and I find myself tightening them significantly when I first put them on, feet go numb for like 3 runs and then it usually starts to mellow out after that and I'm fine. Yes, I was fitted by a professional boot fitter, and I also have custom insoles, stock Intuition liner though.
It's always the lower part of the side of my feet, kinda right above the middle of my sole. I get bruising afterwards, or they're just uncomfortable while skiing.
I'm like 90% park, so I'm choosing control over comfort here, any looser and I ski with a loose foot and feel weird, so it ends up being tight to keep that control.
Is there anything I can do to combat this? Have a tight fit without the discomfort?
