Edea Ice Fly - The boot allows for zero lateral ankle movement; and my coach said that the coaching conference said that the is best for advance skaters (which is you).
I have Ice Fly for a year. My first month was HELL. I have foot and ankle issues (plantar fascitus, heel bumps, ankle tendon). The footbed arch was not moldable enough. The Edea insole sucks. It's just a thin pad (like a panty liner . . .really). I had to buy custom orthotics, (to the tune of $700). You could try those Yellowfeet/Bluefeet (for about 50). But, if those don't work, then make sure you can afford orthotics on top of the expensive boot. With the orthotics, I'm very comfortable, stable, and feel power.
The "lace strap" (accessory) is a must. I don't like all the "bend forward" that the boot gives. It can get loose feeling, but the straps hold things together. I also wear bunga pads, because I want that level of support around my ankle.
The Ice Fly is lighter. It will mess up your camel spin for a few weeks as it's like going from ankle weights to no ankle weights. The heel is high. You will be scratching your toe pick for a few weeks.
In the end, a skate is a skate. Our brains adjust. Kids that get the Ice Fly adjust in a few hours. It took me a few weeks/month. But, I will still scratch on my loop entrances. Not the skate's fault. It's me. I'm sure Max Aaron could do a double toe loop in rental skates. I, honestly, don't know if I would pick Edea again. But, I got too much invested in them now.
Oh, Concerto are lower than the Ice Fly, but are a much tougher skate. My fitter (one of the best in the nation) said that the Concerto is better for men, but just too stiff for women. Top level men break down the Ice Flies in just a few months, so he's putting them in Concerto with no problem. He has mainly men pairs skaters, at a top rink in the country.
