It is extremely rare for someone’s feet and their stride to be perfectly balanced and equally weighted. Some people have feet that visibly turn inward or outward, while others have a subtler inner or outer weight distribution.

It’s hard to see, unless you look at the bottom of your shoes or have your feet scanned with the Foot Levelers Kiosk or other Foot Levelers scanning technology. (Click here to find a provider near you.)

Pronation and Supination

When bodyweight is placed on the outside of the foot while walking or running, it is known as supination. When the weight is placed more on the inside of the foot, it’s referred to as pronation. An easy way to differentiate and remember the difference is that supination has “up” in the word. In a proper stride, the foot should move from heel to toe with a person’s bodyweight evenly distributed on their feet, giving them neutral pronation. read more
