Why is rooting so important? Keep in mind that your foot is the platform in which the rest of your body works and functions optimally. The majority of people look past rooting, seeing it as one of those minute details that doesn't matter as much. They'll end up chasing TFL pain, movement dysfunction, knees caving in, or whatever it may be. But it turns out- it actually had to do with rooting your feet. This is one of the big primary things we need to focus on and develop, because otherwise the rest of your body won't be functioning optimally.
