WelStand’s Casual Top Cover is designed to be used in any of your everyday casual shoes. 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 casual shoes for cushioning for all day comfort. As with the WelStand Sport Top Cover, the Casual Top Cover is also designed to be machine-washed and air-dried, giving the insole a longer life than competitive brands. Package contains one pair.
