* 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.
