More detailed response:
* One option is to go see a sports podiatrist experienced with figure skates. But that wouldn't be my first recommendation in your instance now: (1) They are hard to find, and (2) Your situation is unstable (you've been off ice for two years, and you're breaking in new boots).
* Any off-the-shelf insole will be hit or miss. It's not viable for an off-the-shelf unit to suit every combination of boots and feet. I know a bunch of people who have used Superfeet Yellow. As expected, there's no consensus: A few love them, a few hate them, and many are, "Eh, they kind of work, I guess." [I just ran into a friend at one rink last week. She just bought a pair, and they made things worse.] I've seen them in two pro shops that specialize in figure skates. Techs there told me the same thing: They work for some people, they don't work for others. There's no way to tell in advance. But be aware that they need to be trimmed to fit your boots. So you can't return them if they don't work. If you decide to go this route, I would recommend that you try the cheapest Superfeet Yellow, not the more advanced (and more expensive) ones. If they don't work, you're out only $35 or so (Amazon price; usually higher at pro shops). One big disadvantage of the Superffeet is that they are an all-in-one unit, combining heel lift, heel cup, and arch support. Many boots already have high heel pitches; adding even more heel lift could be undesirable.
Superfeet also makes advanced insoles that are heat moldable, and even ones that are custom 3D printed. I don't know anyone who's tried them.
* An alternative (not mentioned in the article) is the Riedell R-Fit kit (
https://www.ice.riedellskates.com/Catalog/Accessories/R-Fit-Footbeds). Sells for ~$55 on Amazon. This is a modular kit that allows you to vary different components independently (longitudinal arch support, metatarsal arch pad, heel lift, heel wedge). Worked well for one skater I know; didn't work for two others. A more flexible solution than Superfeet, but again you won't know whether any of the components will work for
your feet and
your boots until you try them.
* I personally use individual arch supports, similar to what WednesdayMarch uses, but by Pedag (
https://www.amazon.com/Pedag-Symmet...1?keywords=pedag+step&qid=1639513675&sr=8-1); cost is only ~$11 They come in different sizes, and can be applied at different positions on a flat insole. Out of the box, they use double-sided tape for attachment. That tends to come loose easily, so I don't use the supplied tape, and use Velcro tape instead to attach them to the flat insoles. This allows me to change the position or even swap them out for a different size easily.
You can further customize them with layers of moleskin, moleskin foam, or Velcro tape. Trial and error is needed. The Goldilocks approach: This arch support is too high; this arch support is too low; this arch support is just right. Pedag also makes metatarsal pads and heel wedges, which can also be attached to the same flat insole via Velcro tape: so you can readily swap out components and move them around.
* Hope all this isn't too confusing. If you need clarification, please ask.
