In the BIRKENSTOCK QS/QO models, the anatomically shaped footbed can be updated and replaced. As with the original BIRKENSTOCK footbed, this footbed is also modeled on the footprint of a healthy foot. The midfoot support takes the strain off the forefoot. Important: please note that the antistatic properties can only be maintained in combination with the original replacement footbed. This means: this is not the case if a regular footbed is used. Specifications: Anatomically shaped cork-latex footbed Upper: cork Footbed lining: microfiber Suitable for our QS/QO models with a removable footbed of the same width
