GuideRails support keeps you in your preferred stride when you need it. GuideRails empower your foot’s natural range of motion — because there’s no right way to run, just your way to run. When you need them, GuideRails engage to keep your shins, knees, and hips in their preferred alignment. So you and your shoe work together to keep you in your stride. All runners benefit from some kind of support, but we don’t need it all the time. GuideRails intervene when you could use a nudge back into your preferred stride. GuideRails technology starts with the knee. When the knee is happy, so are your feet, your hips, and back. And when that’s all happy, so is your run.
