Birkenstocks fit true to size on most customers. Your feet should be able to move freely without your toes hitting the edge of the footbed. The Birkenstock shoebox features a handy foot measuring template.

Birkenstocks come in two widths, a narrow width and a normal width. In general we carry the narrow width for sizes 40 and below (sorted as women's sandals in our web store), and the normal width for 40 and up (sorted as men's).
