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.
