Walking in our gym sandal is surprisingly different! The Madrid sandal exercises the foot and leg muscles with every step you make. Work out as you walk with the Birkenstock fitness sandal! You will feel the difference from the first step on. This classical model has a buckle, which provides an individual adjustment and encourages the natural rolling movement of your feet and favours an overall feeling of well-being. As the heel rises from the footbed, the toe is stimulated by the unrolling of the bale to actively grip movement, while the entire foot and calf muscles tense. When placing the heel of the back muscles relax completely. This natural change between tension and relaxation not only provides for the training effect, but also enhances the blood circulation.
