WHAT ARE PRONATION, OVERPRONATION, AND SUPINATION?
Simply put, pronation is the body's built-in means of absorbing impact.
When you walk or run, your foot naturally rolls slightly inward to lessen the impact pounding the pavement has on your body. That natural movement is called pronation. But some people's feet roll too far inward—that's called overpronation. And when the foot doesn't roll inward enough or even rolls outward instead, it's called supination.
Overpronation and supination don't allow the body to optimally distribute impact, which can increase the chance of injuries—especially stress-related injuries. But wearing the right shoes can help, and we offer a number of options for people who either overpronate or supinate.
Wondering if you overpronate or supinate? First, take a look at the wear pattern on the soles of a well-used pair of running shoes. Overpronation can cause excessive wear on the inside edge of the soles. Supination can cause excessive wear on the outside edge of the soles. Then place your shoes on a flat surface—an inward tilt indicates overpronation, an outward tilt indicates supination.
Overpronation is common in runners with flat feet, while supination is more common in runners with high arches.
