A full length, supportive and stabilising model, based on the traditional Blue Footbed by Birkenstock. The Blue Footbed has been supporting the natural foot anatomy for almost 100 years and enables walking as intended by nature based on the principle of the impression left by a healthy foot from walking barefoot in sand. The microfibre footbed lining ensures a natural foot climate in sneakers or enclosed flat shoes , and is easy to clean. The anatomically shaped core stabiliser ensures an even distribution of pressure along the whole sole of the foot. Ideal for those desiring Birkenstock comfort while wearing enclosed shoes and sneakers.
