The Blue Footbed by Birkenstock has been supporting the natural foot anatomy for almost 100 years and enables walking as intended by nature based on the principle of walking barefoot in sand. It is based on the impression left by a healthy foot in sand, creating a natural environment for your feet. The textile footbed lining ensures a natural foot climate in sneakers and is easy to clean. The heel area is cushioned and stabilised thanks to the raised design. This also supports the natural arches of the foot. This makes the Blue Footbed in the form of a half-sole ideal for all those who want to enjoy the unique Birkenstock comfort while wearing enclosed shoes.
