As stated in my previous 2 posts on pronation there is a camp that advocates stabilizing the foot in a neutral position based on the unproven theory that this is the most functional configuration for skiing.
A neutral position of the foot is an alignment in which the foot is neither pronated or supinated. In a neutral configuration, an arbitrary reference axis would not deviate when the other major joints of the foot and leg; tibial-talar, knee and hip joints, articulate.
The graphic below shows three configurations of the right foot: Left – pronated 20 degrees, Centre – neutral, Right – Supinated 30 degrees. According to the camp that advocates stabilizing the foot in neutral with footbeds and alignment, the foot should not pronate or supinate in skiing.
Stabilize literally means to prevent change.
Before taking this theory to the ski slopes to assess the impact, let’s have a look at how stabilizing the foot (actually, the feet) in neutral affects the ability to align forces when standing on a flat, horizontal, solid surface.
Well, this doesn’t seem to work too well does it? In fact, it doesn’t work at all. But hey, this is quiet standing on a flat, solid, horizontal surface. Nothing like skiing when the feet are on edge. Things will be different in skiing….. won’t they? We’ll find out in the next post.
