Rotational feet, Or: I thought pronation was bad!
We all think of the movement at our feet happening in a straight line, along the line of the bend of the ankle. But in healthy walking there is a rotational movement at the foot as well, with the midfoot rolling down and into pronation and then up and out into supination.
Pronation has got a bit of a bad rep in recent times, with running shoe companies selling shoes that will prevent pronation. But it is not the movement of pronation that is bad in and of itself. What is unhealthy is over-pronating so that the foot essentially collapses, or being stuck in pronation (collapsed arches) so that the foot doesn’t move rotationally at all. Just as unhealthy is being stuck in supination (excessively high arches).
Pronation and supination are part of the normal chain reaction of gait, where the body’s interaction with the ground and gravity (don’t ask me to explain the physics!) means that the foot should roll in – pronation – as you land on the ground and then roll out – supination – as you push off from the ground. You can’t consciously make these things happen as you walk, they are simply the foot’s reaction to the ground below and the body above. But if your foot is not able to move in and out of supination or pronation when you are trying to make it happen, it is extremely unlikely that it is happening properly when you walk. And if it’s not happening properly, you are compromising the structures further up the chain of your body – your knees, hips, spine, possibly even your shoulders.
Try these simple assessments to see if your feet move when you rotate:
If you think your feet are lacking sufficient movement, encourage more of this pronation/supination movement through your feet with some massage and gentle exercises (courtesy of James Earls (Anatomy Trains) and Joanne Elphinston (JEMS):
If you always walk in shoes with rigid soles you are limiting the normal rotational movements of your feet, which can result in stiff, painful, unhealthy feet. And remember, you can’t consciously make this pronation/supination happen when you are walking – it is a mechanical response in your bony and soft tissue structures to the interaction between your body and the ground.
