Most Birkenstock styles are available in 'regular' or 'narrow' width.

Narrow width is suitable for narrow to slender feet.

Regular width is suitable for normal to wide feet.

If you already own a pair of Birkenstocks or are trying them on in store - check out the little foot symbol on the footbed. If the foot is coloured in, it's a narrow (N). If it's just an outline of a foot, it's a regular (R).

    The sole was perfect, so comfy, but the ankle was horrible. The fabric was so stiff and hard it really hurt my ankles on the back within about 5 minutes of wearing it, I decided to return them as I wasn't sure how well the microfibre fabric would "break in", and its summer in australia, so too hot for thick socks. I wanted the leather but opted for the microfibre as leather was sold out. Otherwise the customer service has been decent so far and shipping and everything else was great.

    TLDR; Sole good, ankle too stiff, going to buy a different pair when the leather comes back in stock

    All I wanted and more

    Fantastic footwear, I’m a chef and have been using Birkenstock For years now but first time using boots, and the enclosed ankle plus the insole support are relieving a lot of street from my feets

    Look nice but no banana

    Nice-looking, but in reality too narrow, too inflexible. I thought 'microfibre' meant that they would be softer, like fabric, but they were stiff and plastic-feeling. I ended up sending them back.
