The Original Birkenstock Footbed
A legendary design
The heart of all models is the original BIRKENSTOCK footbed. The construction, which has been thought out to the smallest detail and makes it feel like you're standing in sand, helps your feet feel as comfortable as possible for hours on end. This supports health and promotes wellbeing.
Deep heel cup
The very deep molding in the heel area supports the foot tissue and holds the heel bone firmly in its natural position. This provides the foot with nearly as much support when it is in a sandal as when it is in a closed shoe.
Heel mould
Activates the calf muscles, stabilises the back of the foot and improves gait and coordination.
Interior and exterior longitudinal arch supports
The arch supports that run alongside the sides of the footbed surround the tarsal bones inside and out. This gives the foot the stability it needs when it takes a step.
Transverse arch support
The support that runs through the middle of the footbed stabilizes the metatarsal bone. In this way, the transverse arch support helps ensure that the foot has a naturally straight and solid stance.
Toe grip
There are raised indentations at the front of the footbed near the toes. Thanks to the toe grip the toes remain loose and spread out in their natural position. The indentations also support the natural rolling motion of the toes.
Footbed edge
The footbed is drawn up especially high at the front. As a result, the high footbed edge protects the toes during the rolling motion of the foot.
