It is based on the impression left by a healthy foot in sand, creating a natural environment for your feet. The heel area is cushioned and stabilized thanks to the raised design. This also supports the natural arch of the foot. The Blue Footbed is therefore ideal for anyone who would like to enjoy the unique comfort of BIRKENSTOCK in enclosed shoes made by other brands too.
