As an owner of 12 pairs of Birkenstock sandals, I can say that they NEVER disappoint. The fit is fabulous because the straps are adjustable. The foot bed is the most comfortable one around and makes these shoes the perfect solution for people who want to wear sandals, but may have foot or arch problems. One cannot put an orthotic insert into a sandal. These are the best alternative and they can prevent futre problems as well by aligning the foot with the rest of the body.
