I have have other Birkenstock shoe forever and want to try the soft footbed . to be honest , I can not tell much difference . these be totally comfortable , but my old one be too . probably the best thing be that since they adjust in two place -lrb- the strap -rrb- , they can fit even when my foot be swollen . I be fly cross country in a couple day and will be wear these on the plane because they be easy to slip into and will be comfortable even if my foot swell on the long flight . since I be only take a carry-on , I can use these as slipper when in the motel and save space in my carry-on suitcase . with airline price so high for luggage , they be save I money . shoes\/sandles that can be multipurpose be precious .
