We have stayed in various shoe stores looking for good slippers. Almost everywhere there were only some who have smelled from a distance by chemicals and solvents. Who wants to do that to his children? Or the shoes were too narrow and could not be adjusted. The Birkis the first impression was the same very different. Neutral odor, great fabrication, well adjusted and easy fit, to an enthusiastic daughter. Since we buy for kindergarten, home and school now only Birkis and can absolutely recommend. For us, the shoes are worth every euro.
