In Japan, it is customary for guests to replace their outdoor shoes with house slippers when entering a residence. These cone-shaped slippers feature a unique design that allows for easy storage. The 'Triangle Roomshoes' are a pair of simple slippers that feature no clips or fastenings. The slippers are designed to fold at the wearer's instep, which allows them to stay on without the need for a [heel covering](https://www.trendhunter.com/trends/moondeck). The shoes are tapered at the toe, which gives them a distinctive cone shape. When not being worn, the unique design allows consumers to [stack the slippers](https://www.trendhunter.com/trends/rotating-shoe-rack) on top of one another.
