All Fläpps wall shelves with a small depth can be converted into a shoe rack in a few simple steps. By inserting small magnetic pins into the guide rails of the hinges, the flaps of the shelves open only 45 degrees, allowing practical storage of shoes and other things that can be stored at an angle. Fläpps shoe shelves have one thing in common, they provide practical storage space for shoes and more, especially in small and narrow hallways. The wall shelves remain flexible even with the add-on and can be folded away or reused as shelves as needed.
