Did you know between 60 to 80 percent of people suffer from overpronation?

And, no, that doesn’t mean being excessively excited about a country.

What is pronation?

The opposite of supination, pronation happens when the heel bone comes inward and the arch collapses. It almost creates an inward roll of the foot. Over time, those who overpronate will wear down boots and shoes quickly in the toe area. Even worse, it can cause some painful foot problems including knee issues, shin splints, Achilles tendinitis and plantar fasciitis among other things.

On the other hand, supination, or underpronation, occurs when weight is supported by the foot’s anterior. When someone suffers from supination, they might appear bow-legged. Both over and underpronators suffer from shock absorbing inefficiencies.

The solution? Stiff shoes or boots for overpronaters; flexible shoes or boots for underpronators. Now everybody is happy.
