The Boulder Running Company was the first running store in the country to offer our customers a free video gait analysis, and we pride ourselves in continuing to offer this service today. The Gait analysis process: A video taped gait analysis helps determine the best shoe for your unique foot and stride. Ideally, when we tape you, your arches should remain in a neutral position throughout the gait cycle. In other words, excessive inward or outward rotation of your feet and ankles is a bad thing. Neutral, or straight (no inward or outward rotation) is ideal. Our fitting process begins with a videotape of you running or walking on a treadmill to see what specifically your foot is doing with each stride. Many runners and walkers overpronate, which occurs when your arch is allowed to collapse excessively, allowing too much inward rotation. This puts pressure on your knees, hips, shins, etc, and causes many common running injuries. Fortunately, it is fairly easy to solve with a supportive pair of shoes or over the counter orthotic device.
