HOW TO GET THE BEST FIT
Unbuckle all the straps and place your feet in the sandals. The contours of the footbed should correspond to your own arches. Make sure that your heels are in the heelcups and the toe bar should fit comfortably below your toes.
Most BIRKENSTOCK footwear is available in two widths; REGULAR and NARROW. Your feet should rest comfortably within the protective rims of the footbed when you stand. There should be about ¼ inch of extra space at the front of your toes and at the back of your heels, and 1/8 of an inch on each side of your feet. Your feet will need extra room when you walk. Proper length and width are crucial to your comfort. A correct fit will also help increase durability.
