Excessive pronation is the most common form of biomechanical imbalance to affect the feet and can cause a wide range of foot problems and injuries. Pronation is a natural part of the gait cycle and is required to help propel us forward when we walk and adapt to the ground as our foot strikes the ground. Excessive pronation can either be overpronation or supination.
Overpronation is when the foot rolls inward and excessive amount and supination is when your feet roll outwards an excessive amount during the gait cycle.
If you have excessive pronation like this it can leave your feet more susceptible to foot injuries such as plantar fasciitis.
This is because over pronation creates more tension on the plantar fascia and can cause it to become overstretched and inflamed more easily.
Excessive pronation can also cause strain and pain to develop not just on your feet but also on other parts of your body as well, such as your knees, hips and lower back. Your feet must support your entire skeletal system and when there is an imbalance in your feet this can affect your entire posture and cause strain to develop elsewhere on your body.
One way to see if you have excessive pronation is to examine the soles of your shoes. If you have high are fallen arches you are more likely to develop excessive pronation. Those who supinate will find that there will be more wear on the sides of their shoes than anywhere else, whilst if you have over pronation the wear will be mostly around the toe box.
Orthotic insoles can help to correct supination in your feet by using arch support to stop your feet from rolling outwards when you walk or run. Arch supporting insoles can also help to ease pain and allow your feet to recover properly if you have an injury by taking the strain off your feet.
