Unfortunately for my situation, my skates felt fine and completely did not hurt when I tried them on and when I walked around in them at home. However, once I got on the ice and just went around the rink for leess than 10 minutes, my feoot started to cramp up and hurt a lot. At that point, it was too late to return
From reading your older posts, you bought these in some sort of big box store, not a pro shop, right? I would honestly suspect that they're just not the right size.... most skates are a little uncomfortable (because they're tight/stiff) until they are "broken in" - that's just the nature of how they are... skates are supposed to fit very close to your feet. If they've never hurt you when wearing them, then something isn't quite right, and I would bet they're too big.
Assuming they aren't the completely wrong size, cramping can be caused by a lot of things.. inadequate arch support (or too much), or if the ball is too wide or narrow are two of the bigger causes. You could pronate and need a post wedge. You could even need metatarsal support... all of those are tiny things that can be done to help support your feet better. The insoles of Jacksons and Riedells are removable.. that won't account for differing arch support built into the last the boot was made on, but in a lot of cases you can put something else in (like superfeet which you tried, but there are others) that may work better. Custom orthotics are an option - even in stock boots, but if you go that route you would end up spending more on orthotics than your boots. You'd be better off working with a fitter who knows what they are doing and can make the small changes to help support your feet better, but you can modify the insoles yourself by adding more foam in places you might need it. Pretty much if there is any 'open space' in your boots, it needs to be filled.. because you're left with either a gap that will allow your foot to move and cause blisters, or it's showing an obvious lack of support for some part of your feet. I can't tolerate any extra space in my boots except for maybe a couple of millimeters past my toes.
There's also a possibility that the cramping is simply you using muscles you aren't used to using - skating uses different muscles than walking does, and some aren't used to the workout. I know that my feet are usually not happy any time I haven't been skating for a while (months, years...), but that tends to go away within a few weeks back on the ice, as those muscles build back up again. If your feet cramp while skating, I'd get off the ice, take off your skates, and massage your feet for a few minutes, then get your skates back on and go again... you might find that it helps a bit.
I've never worn Reidells, because they are just made all wrong for my feet... everyone's feet are different and no one brand is going to work for everyone.
