Thinsole™ orthotics deliver comfortable support with less bulk than other insoles, making them perfect for dressy or casual shoes and can be worn in shoes with and without removable insoles. They are designed to support your foot’s arch and absorb the shock of everyday activity. The unique shell provides excellent stability without the added bulk of most orthotics. The shell is bonded to a layer of closed-cell nitrogen-injected Spenco® Material and covered with 4-way stretch nylon.
