Lynco® Biomechanical Sports Orthotics are designed specifically for comfort, support and weight redistribution in athletic, walking and comfort footwear. The L425 is a posted sports orthotic designed to provide comfort for conditions usually associated with flat feet such as plantar fasciitis and heel spurs. These orthotics feature rearfoot posting and longitudinal arch support to help realign the rearfoot and control the over-pronation. Additional metatarsal padding provides forfoot comfort. These tri-density orthotics feature a Pro-ShoxTM 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.
