This is my second pair of the Softbed Arizonas. I have been wearing Birks for over 30 years; the Arizona's are the most comfortable of all the styles and the Softbed really adds an additional level of comfort. The price was much lower than other vendors I had checked and I love wearing them. No breaking in period necessary! The regular, as always w/Birkenstocks, is a wide. I have a wide foot, and it's plenty wide for me even on the tightest notch, so keep that in mind when ordering Reg. verses Narrow.
