WelStand’s Sport Top Cover is designed to be used in any sport or athletic shoes, providing extra cushioning and comfort. Installation of WelStand insoles is easy. First, remove the factory installed footbed from your shoes, then simply attach the top cover to the WelStand Orthotic Footbed, slip the insole into your favorite athletic shoe and you’ll be ready to go! Unlike other orthotics that need to be thrown away when dirty, WelStand’s Sport Top Cover can be washed, air dried and ready to reuse in no time! Package contains one pair.
