Lynco® Biomechanical Sports Orthotics are designed specifically for comfort, support and weight redistribution in athletic, walking and comfort footwear. These tri-density orthotics feature a Pro-Shox™ top cover for superior cushioning and shock absorption. Pro-Shox's high-tech polyester fibers wick moisture away from the foot and provide a cool, friction free surface to prevent blisters and other foot problems. Lynco Sports Orthotics feature a molded Pedic® core for stability and resilience, while the Plastazote® bottom conforms to the footwear and keeps the orthotics light in weight.
