Boot Stay is another brilliant patent-pending invention by Fashion First Aid. Slouchy boot and saggy boots are two totally different things. Boot Stay is designed to keep boots up, preventing the user from having to tug at the tops of their boots all day. It's made of a stiff vinyl stay covered in soft 100% cotton. It prevents cankles by adhering to the inside of boots and keeping them nicely stiff and straight instead of flaccid and wrinkly. While we can't do anything about your actual ankles, we can prevent you from having the sloppy cankle look in your cute boots.
