When you walk or run, the impact is directly on your foot, but how your foot strikes the surface can impact your body. All people naturally pronate while walking or running, as it is the foot's natural movement. The issue with pronation is how intense the degree of movement is with the inward rolling motion of the foot as your heel strikes the ground and the arch flattens out to help absorb shock.
This natural movement is a bio-mechanical process of the human body, and why we at Healthmark say, “The foot is connected to the rest of the body, and your health starts here.”
The degree of pronation varies from person to person, and some individuals exhibit a more pronounced inward roll than others. This can cause and increase the risk of injury in the foot, ankle, hips, and back- especially on unforgiving surfaces- as these areas are forced to move in an unnatural manner.
Underpronation, also called supination, happens when the foot rolls outward too much during walking or running, leading to uneven weight distribution across the foot and potentially causing problems such as ankle sprains, plantar fasciitis, or stress fractures.
What you need to know about Pronation
Pronation and underpronation (supination) are normal, necessary movements of the foot. When the range of motion becomes excessive one way or another, then clinical symptoms occur.
Pronation problems stem from arch issues- higher arches tend to underpronate, while those with lower arches or flat feet tend to overpronate.
Inserts can be helpful in treatment, but a podiatrist is best to consult with in identifying the pronation problem and treatment plan.
