When the outside part of the heel of your shoe wears significantly faster than the inside, this is a sign that a person is over pronating when they walk/run. Excessive pronation of feet, or flat feet as it is commonly known is where the arch of the foot collapses as a person walks and the feet roll in. This can be caused by a number of things including ligamentous laxity, leg length inequalities, weakness/tightness in the calf, and other general anatomical variants.
What does this cause?
The feet are the foundation for your body and excessive pronation of the feet will frequently lead to altered lower limb and pelvic biomechanics which increases the risk of injury throughout the body especially during walking and running. As seen in the image below on the left this can cause problems throughout the entire body as force is transferred up through the legs from the feet all the way up to the neck/head. The right image shows how the body is supposed to look when aligned correctly
Pronations of Feet
This disruption to normal biomechanics can then manifest itself in the signs and symptoms such as
Tension and pain being felt in the arch and sole of the feet.
Shoes wearing down faster on the outer side of your shoes.
Pain that may be felt in the ankle, shins, knees, hips and lower back during standing or physical activities such as running and walking.
Increased tension in the lower leg musculature.
