Highlighted Features Mimics the natural footprint of walking barefoot on sand Deep heel cup cushions and stabilizes with every step Contoured arch support promotes natural alignment High external side walls add stability inside closed shoes Thin, flexible profile fits most closed footwear Brings Birkenstock's footbed comfort to shoes outside the brand Description The Birkenstock Blue Footbed brings the brand's legendary support into shoes that were not built with it. Made from BirkoCork, a natural cork and EVA blend, it is shaped with a deep heel cup and contoured arch support to encourage a more natural, barefoot-like stride. The thin, flexible profile slips into most closed shoes, from dress shoes to sneakers, without taking up the room a bulkier insert would. It is a practical option for anyone who already loves a Birkenstock footbed and wants that same support and posture help in everyday footwear, for walking, work, or casual wear in any season. Materials: Footbed: BirkoCork (natural cork and EVA blend) Care Instructions: Wipe clean with a damp cloth Air dry after wear Do not submerge in water
