Abstract: A double-sided adhesive retainer for footwear and other apparel is described. An embodiment of the present invention includes a core composed of a polyurethane foam cushion. The core is flexible and can conform to the shapes of the inside of a shoe and a wearer's heel and/or foot. On one side of the core is a layer of adhesive that stays permanently affixed to the core and can be used to removably attach the device to the inside of a shoe. On the opposite side of the core is a second layer of adhesive that is also permanently affixed to the core and can be used to removably attach the device to the wearer's skin or any apparel worn on the wearer's foot or ankle. The device described is therefore able to ensure that a shoe remains attached to a wearer's foot.
