I have to comment on Flavius review, concerning Birkenstock width:
I am a woman, petite, medium built. My feet are not particularly slim nor noticeable wide.
Contrary to what Flavius wrote, I find "Regular" Birkenstock width to be just "Regular": the right width for me.
Birkenstock mentions that the sandals are to be roomy and recommends that feet should fit completely inside the footbeds, even if they feel big on 1st try - only if your foot moves side to side when you walk and adjusting the strap does not help, you should go with narrow fitting.
If I would wear "Narrow" width, my feet would be pressed against the rim of the sandals - that would feel more similar to most of my other shoes, but the whole purpose here is to have footwear that is comfortable and can adapt to my shape, instaed of me adapting to the shoe shape. Please note that despite looking for comfortable shoes, I a am fashion conscious person and would not feel good if these would look unreasonably wide.
So, as always, your mileage may vary...
