Sole Sanctuary is one of the most sophisticated shoe-storing inventions that enables users to have their personal and professional shoes stored and dispensed efficiently. It means that this novel approach focuses on the provision of the activity and the use of technology to provide the consumer with an engaging and efficient medium for their needs. Every rack fitted in the shoe space has an in-built camera and germ scanner in such a way that users can easily scan shoes and ensure their cleanliness. There is a front-facing camera at the display rack as a means of assisting the user in picking matching shoes with his or her outfit for the necessary and desired coordination.

First of all, the users need to download the Sole Sanctuary application to their portable devices and provide information about owned shoes, wear frequency, and the expected life duration of the shoes. Some of the functions of the app are to recommend suitable shoes to match part of the outfit, to inform the user there are shoes available that have not yet been used or have expired when the rack is full, and to detect when the shoes are untidy according to the germ scanner camera. It also helps users to be aware of the new and trending shoes in the market for easy browsing and purchasing operations.
