I have been selling shoes for a long time. In my years, I have wondered why the best selling models of each brand happen to be the mid-mileage trainer. Only about 10% of customers leave here with a shoe in the stability category. Recently I have started using Dartfish Gait Analysis and it has revealed a lot about why certain people need certain shoes. In this blog I will talk about how Gait Analysis helps with pronation.
By definition pronation is the rotational movement towards a prone position. In running, a moderate degree of pronation (the tendency of the foot to roll to the inside) is good; it happens to be the body’s natural shock absorber. Without slight to moderate pronation, impact from landing (particularity for a heel striker) transfers directly up the skeleton resulting in pain in the knees, hips, and lower back. This impact may be a contributing factor leading to other lower body injuries such as shin splints, achilles tendonitis, and IT band pain. The shock absorption associated with pronation simply and effectively softens the landing.
