This shoe is made of odorless and pollutant-tested plastic EVA. Straps and sole are made in one cast and are therefore particularly robust and durable. Thanks to the thorn buckles, the straps can be adjusted to your foot. The elaborated footbed is your extra for pleasant wearing comfort. Footbed info: The heart of all models is the original Birkenstock footbed, which is modeled after the natural footprint of a foot in the sand. Thanks to this, walking in Birkenstock shoes is like walking barefoot. With its anatomical shapes, it optimally supports your feet during natural stepping. Feet, joints and back are protected. At the same time, the foot and leg muscles are trained. This promotes health and well-being.
