BTW, I suppose it is possible that what I see as an inward warp, could just be the shape of her feet, and have been produced by the heat mold, rather than a sign that they are breaking down and not supporting her feet any more.
I have mixed feelings about flex notches. It's possible they make the boot break down sooner. OTOH, they can obviously make a boot more comfortable. I eventually had notches cut in my Klingbeils, and it helped.
I think 1 year lifetime is fairly plausible for good custom fit boots (which should last longer, due to better fit), with the number of hours of presumably-freestyle skating she is doing. I've heard (I think that was from Mike Cunningham too) that 18-24 months is more typical for good properly custom fit boots, used for Freestyle, on people whose feet are no longer growing, but there is a substantial range of variation for different athletes. It's an unfortunate fact of life that good athletic equipment designed for optimal performance can't last forever. Extremely high boot lifetime also isn't compatible with ideal comfort, lightness and functionality. For example, I was once told that for Harlick's lightest boots (which were lighter than Edeas), 6 months might be more typical lifetime.
Sure, some people's, including mine, last longer. But I don't jump much, and probably am not as strong as a good athlete, even a young lady. I had single layer Risport boots break down in a few weeks. (Possibly because I was taught to use deep ice dance edges.) (They were used, but showed no signs of wear whatsoever - the kid must have been growing very fast.) But I've gone back to my approximately 13 year old Klingbeil Dance boots, that must have a few thousand hours on them by now. But must of what I've done on them is more or less ice dance, NOT freestyle. And Klingbeils, which were essentially all leather, were heavy boots made of very durable materials, that were expected to last a long time. Plus, mine were rebuilt by Klingbeil, after 6 years. They are now quite broken down, but are finally comfortable as long as I don't try anything beyond an occasional Waltz jump, and are sufficient for what I mostly do. When I was trying to jump more, they weren't adequate. If I needed extra sideways support against pronation or supination, I suspect they wouldn't be adequate for that either.
I tried SuperFeet (both the shoe and skate models) and a number of other brands of insole, in skates, shoes, hiking boots, and XC Ski boots. The problem with SuperFeet, etc., is that they are a specific shape, which might not happen to be what your DD needs, to make her particular feet work with her particular boots. The end result is that some people love them, and some people hate them. And also means that most people have to adjust their shape a fair bit to get a really good fit - which, done right, is about as much work as making your own insoles from raw materials, like foam, but SuperFeet are much more expensive than raw materials.
The worst, from a customization perspective, were gel-filled insoles. They weren't stable enough for precision edges, and you can't cut into them to make adjustments without loosing the gel. OTOH, they might have been fine for walking or running shoes, or XC boots.
I tried one type of heat mold-able rigid insole - I forget the brand. They worked moderately well for a short while, but eventually pushed out those boots at the bottom. Though, again, those were single-layer boots. Good quality double layer leather boots, with an additional stiffening layer in between, like any high level boots have, would have undoubtedly lasted longer. That caused them to wear out and be too wide for my feet quite quickly, and they eventually started rocking and being unstable. I concluded that I would never try heat molded insoles again.
I've concluded that making your own insoles, completely customized to your feet and body, works better than any insole or consumer market "orthotic" you can buy - IF AND ONLY IF you have the foot sensitivity to feel where the high and low pressure points are on your feet, how your feet are deforming as you skate, and the analytic skill to figure out what you individually need your insoles to do. It gets more complicated if your daughter isn't mature enough to do that herself, and you have to do it for her, because she still has to be able to describe to you precisely what she feels, and if she lacks the sensitive or analytic skill to do that, it can't completely work, no matter how hard you try. Maybe if you had the pressure sensitive socks that some podiatrists use (they connect to a computer) to map out pressure points, as their customers move - but I'm not even sure that non-medical people can buy them, the total set up must be expensive, and you'd have to learn how to use it.
However, completely customized boots, like I think Harlick is capable of making, if both the fit and post-production final adjustments are done by someone who really knows what they are doing, like Harlick's own factory reps (one of whom, Phil[?], I think, used to be their master boot maker), ARE, in effect, fully customized orthotics (which are the same thing as custom insoles, but are made or modified by a professional), specifically designed to work with her feet. So, at least at first, if all that is done completely right, she wouldn't need different insoles than they came with - and they could theoretically be even better than making her own insoles, because the customization could cover the entire feet. So, if she does need new boots, I encourage you to take her to to Phil (if I remember the name right), or to the factory store, for both initial custom fit and post-production adjustments.
Hope things work out!
