I'm not sure if it's the right forum because it's more about the insole but here goes.
I have pretty flat feet and am using the blue superfeet in my snowboard boots. When I put on my boots, they feel great and I can walk around no problem. Once I start boarding, I get quite a bit of pain in my arches. I have used them 3 times so far. Is this normal or should I throw the stock insole back in? The boots are new as well and have packed out. Used them about 5-6 times now. Some people said it took them 4 times or so before their feet started feeling good but I am using the blue superfeet in my walking shoes and the yellow superfeet in my ice skates with no problems.
Sounds like your boot is too big (not just length but volume).
Whenever my arches ache it's because I'm riding toe side and have heel lift. And when you say they are packed out after only 5-6 sessions, it really confirms that the boot was too big to begin with.
