Pronated (in the fall line) but supinated when turning (left)

post #1 of 5
Thread Starter 
Looking for thoughts here.  I plan to work (more) with my local guy.  It all concerns my left foot.  I do have orthotics but i dont feel i am 100% dialed in.

Toes straight ahead, barefoot, my left ankle is somewhat rolled in.  Running shoes reflect this: worn more on the inside of the left foot. 

Trying to roll outward onto my left little too is MUCH more difficult than with my right. And i can feel muscle tightness across
the top of my foot when i do this (sort of a hurt so good amount of discomfort, not "pain")

When i had cants (under the binding) or shims taped to boots, they were thick side IN iirc

When i do a pivot slip with the ski tips pointed left, several things happen:
   1) it is more difficult to get the upper/lower body separation vs tips pointed right.
   2) my left ski is typically overedged on the UPHILL edge, ie too much drag and i slow down
   3) when i go from two skis in the fall line to both tips pointed left, i often (have to) over-rotate to get the skis across the hill,
       often to the point where the tails end up below the tips.

It seems like when i stand toes forward my left shin comes into my foot slight inside of center, but when i rotate left (as in a pivot slip) the left shin now goes outward of center

FWIW, i found it very easy to rollerblade or watersking going clockwise,  but unbalanced going counterclockwise.  in roller blading, i feel very unstable to have the back left leg cross behind the right front leg (ie when going counterclockwise).

thanks for reading

 Yes this all sounds like an un diagnosed pronation.  All the symptoms you describe quite accuratly can be fixed with internal canting or more accurate foot position.  Yes you have a foot bed but most don't actually stop all pronation.  You should be measrued to see how much you have.  It will change everything.

Though the picture your description creates is not very clear yet, I think that the following link to another thread may help. It seems to be a mirror image (opposite foot) of a similar problem and am curious to learn if you think it might relate to your situation.


As far as the canting, which you properly refer to as an adjustment between the boot and the ski, it would rarely be needed with the thick side inside as a correct solution to an alignment problem.

Let us know what you think.

Hi Ray,
 there some definite similarities.Thanks for the link.  For greater clarity, let me desribe what happens to me in more detail:

Anatomy;  right shoulder is about 1 inch lower than the left.
                cross legged:  right ankle over left knee == fine
                                     left ankle over right knee == very tight from mid thigh to hip socket.
                left foot:  harder to roll onto the outside edge (as in an ankle walk you might do in basketball practice)
                              tuberosity of 5th metatarsal flares out more than on right foot, perhaps this inhibits rolling outward (eversion?)

Dry Land:
Pivot-slip move in bare feet, no skis or boots on. (This is a different than skiing as
here the upper body rotates and the feet do not)

Both feet pointed East, left foot slightly ahead of the right, shoulders also facing East.
If i (try to) rotate my upper body clockwise (to face South), my kneecap want to move in
and my left foot has more pressure on the big toe edge. 

In the same bare foot exercise, but now the right foot ahead and counter-clockwise rotation, both feet remain flat
and upper/lower body separation is easy and comfortable.

On hill pivots slips:
   with the tips pointed to the left I often catch the big toe edge of the uphill/left ski
   typically i lose speed with tips pointed left (compared to pointed right)
   tips pointed right - no problem.
  On hill most runs start with a right turn / most falls are onto my right hip

On hill, bottom half of my left turn - somewhat little too edge heavy on the left foot.  But here the upper and lower body
separation is not nearly as much as in a pivot slip, and the left ski is the up hill / inside ski, so its role here
is perhaps less critical.

Putting it all together, it feels like in the bottom of my left hand turn (or a traverse to the left), the left ski is too much on the little toe edge
However, if I rotated only my upper body clockwise, that torque would want to roll my left foot onto the big toe edge.

Many many thanks for reading
