RAFoot shapes in Frontal Plane
A Simple Way to Understand Foot Inversion and Eversion
Inversion is when the sole of the foot turns inward, toward the other foot or the center of the body.
Eversion is when the sole turns outward, away from the center of the body.
Understanding Pronation and Supination (in Closed Chain)
When it comes to foot pronation and supination in a closed chain (like when your foot is on the ground), things get a bit more complex.
To allow the arch of the foot to lengthen or lower during pronation, and to shorten or lift during supination, the rearfoot and forefoot need act and move move in opposite directions.
For example, to access pronation in the frontal plane:
The rearfoot must evert (you can think of it as your heel is “collapsing” inward slightly,the bottom of your heel is still on the ground — it’s just tilted so the outer edge lifts a bit.
The forefoot must invert (is when the front part of your foot (the ball of the foot and toes) tilts inward, toward the other foot.
Importantly, the lateral heel and 5th metatarsal head (the outside ball of the foot) should stay in contact with the ground.
To access supination, the opposite needs to happen:
The rearfoot inverts and the forefoot everts, creating a lifting of the arch.
This coordination between different parts of the foot was one of the hardest concepts for me to grasp when I first started learning about foot mechanics — so I hope a visual alongside this explanation will help make it clearer!
