My outsole shows a wear pattern on the outside (lateral) portion of my shoe — does this mean I under pronate?
Maybe. Then again, it could mean that you are striking on the outside portion of the shoe and are rolling in at midstance, resulting in over pronation. This is one example of how a wear pattern on the outsole can be misleading. Observing an individual during Video Gait Analysis eliminates the potential for error here by isolating each phase of the gait cycle and providing a clear understanding of foot mechanics.
