A common source of reduced productivity and lost work time in the industrial setting is musculoskeletal discomfort in the feet, knees, hips, and low back. Even when working identical job posts, these symptoms can vary widely between employees, and could potentially be caused by intrinsic foot biomechanics coupled with long-term standing activities. Therefore, to prevent injury and reduce daily discomfort, one size-fits-all approaches such as anti-fatigue mats or off-the-shelf shoe insoles may be less effective than treating each employee’s specific biomechanical traits. The Quadrastep System is a prefabricated, semicustom shoe insert system that bridges the gap between more expensive, fully customized orthotics and off the- shelf options. We studied the effectiveness of the system in a large manufacturing plant by assessing and providing Quadrastep inserts to 28 volunteers. After 2 months of daily wear, 94% of these volunteers said they received some benefit from the inserts, while 52% reported full resolution of daily symptoms.
