Well, since I lost my left orthotic on my vacation, I had to find a replacement. So after skating on the bare bottom of the skate for a few hours, I learned there's a reason for insoles. I went and bought some yellow Superfeet insoles "for hockey players and figure skaters". They're $40 a pair. This is my evaluation.
1.the heel part of the insole should fit in the heel of your boot. If it doesn't fit, return them.
2. you'll need to trim the forefoot of the insole. The forefoot is designed for people with broad feet, or hockey boots. You can do this with ordinary scissors. It helps to have the old insole as a pattern. Since I didn't have that, I flipped over the right insole so I had a pattern.
3. The main advantage of the super feet insoles is that they have a relatively stiff
heel counter. This means that the heel of the insole gently pushes the bottom of the foot in so that you have more cushioning under the heel.
4. I'm not quite happy with the angle of the insole. This is personal, but the support under the insole is sufficiently stiff that I can insert spacers underneath it to angle it. The under sole (the stiff plastic support) is designed so that air can circulate underneath. Unlike other super feet products the under sole is not flat, it has little ridges to give the sweat from your feet an opportunity to evaporate rather than mildew.
Overall, I'm satisfied with this purchase and think it's worth the $40 investment. We'll see how long they last, but they appear to be sufficiently sturdy to last 6 months to a year.
