These
Birkenstock Ibiza sandals are similar to the Birkenstock Madrid available only through the Special Order Program. Upper material:
Birkenstock Birko-Flor made of acrylic and polyamide felt fibers, this material
is a soft fabric with a smooth leather-like finish.
The relationship between the strap and the footbed causes a gripping reflex on
the foot with every step taken. During the gripping reflex, both the feet and
ankle muscles are tensed, as the muscles responsible for the toe movement are
located in the ankles. The muscles are then totally relaxed again when the heel
is set down. In this way, there is consistent tensing and relaxing of the
muscles with every step taken with the Madrid sandals. Gentle exercise for the
feet and legs. In addition, the circulation of the legs is boosted. The model
Birkenstock Madrid also has this affect.
