* If you’re skating and skiing, perhaps you should consider seeing a podiatrist for peace of mind. Any competent podiatrist can check for general foot issues, such as pronation/supination. But, if you should need orthotics for your skates, you would need a podiatrist with specific experience fitting orthotics for skates, since orthotics for skates differ from those for walking shoes or running shoes.
* Unless the skate tech is aware that the skater supinates, it is common practice to mount the blades slightly to the inside (regardless of the age of the skater). But it is totally wacko to routinely mount the blades extremely to the inside, such that the mounting plate protrudes past the boot. You should find another tech.
* For skating, an initial series of tests to check for supination/pronation consists of one-foot glides in a nominally straight line. [Caveat: First check to make sure that your blades have been sharpened properly with level edges.]
- Stroke forward to pick up some speed. Glide comfortably on two feet in a nominally straight line. Then lift up one foot (let’s choose the right in this instance) and continue to glide on the other (the left in this instance). Don't force the glide to control it; just let it flow at ease. It’s best to have another person observe you from the back. Ideally, you should glide in a straight line. If possible, do the test on a clean patch of ice. Look at the tracing. Ideally you should see two lines of equal weight, such as | |. If you supinate, you will be biased towards the outside edge; you will veer to the left, and the tracing will look like this:
| | (outside edge will be heavier). If you pronate, you will be biased towards the inside edge; you will veer to the right; and the tracing will look like this: |
| (inside edge with be heavier). [In extremely screwed-up scenarios, you will see only a single heavy line.]
- Repeat with the other foot: lift up the left, glide on the right.
- Then repeat with one-foot glides backwards.
* Once you’ve made adjustments (see previous post), if needed, such that the one-foot glides are OK, then follow-up with consecutive forward outside edges, consecutive forward inside edges, consecutive backward outside edges, consecutive backward inside edges, forward X-overs (both directions), and backward X-overs (both directions) to determine whether any fine tuning is needed,
*
I have problems getting all forward outside edges, but I'm ok with backward outside edges and X-overs in all directions.
Also I'm guessing that as my blades have been in that position for a few years it's going to be difficult to adapt to having them more central?
Your results are inconsistent. For some maneuvers, you might be fighting to compensate. If you've been doing this for years, you will have a re-learning curve.
