The Lynco L405 Sports Orthotic is designed specifically for comfort, support, and weight redistribution in athletic, walking and comfort footwear. These tri-density Lynco Orthotics feature a Pro-Shox top cover for superior cushioning and shock absorption. The Pro-Shox high-tech polyester fibers wick moisture away from the foot and provide a cool, friction free surface to help prevent blisters and other foot problems. Lynco L405 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.
