Are all Birkenstock unisex?
Most Birkenstock sandals are unisex, however, certain styles are designed with women’s styling and gait in mind.
For example, the classic Arizona is designed in unisex sizes. Styles such as the Gizeh and Madrid however are women’s sandals that do have substitute styles for men (e.g. the Ramses is a toe-post sandal styled for both men and women).
It is worth noting that although they are unisex, Birkenstock sandals come in two widths—M and N—which can help differentiate between the different shapes of men’s and women’s feet!

Birkenstock Sizing
Wanting to invest in a pair of Birkenstocks for yourself but wondering about sizing, take a look at our Q&A to clear up some of the most asked questions.
What does M and N mean in Birkenstock sizes?
Birkenstock sandals are available in two width sizes, M meaning medium and N meaning narrow. The M sandal fits like a regular, so if you have a wider foot opt for an M. An N sandal offers a slimmer fit for more petite feet.
Here at allsole, all our N or narrow-width sandals are marked as ‘Slim Fit’ in the title. The M or regular fit are identified as men’s sandals due to the wider fit better suiting the shape of their foot. If you are a female seeking a wider fit, you can also opt for ‘M’ as they are in reality unisex.
Are Birkenstock true to size?
Birkenstocks are designed to be roomy. They are designed to hold your foot but also give it room, so you don’t usually need to downsize. Measure the length of your foot by standing on a flat surface measure the distance from the back of your heel to the tip of your longest toe. Add 10mm to your foot length to allow your foot room to move.
In order to optimize the great support of your Birkenstocks, we recommend sizing so that your heel sits flush in the heel cup and your toes approach, but do not touch, the front lip. This type of fit will allow the arches of the footbed and the toe bar (the little bump that sits under your toes) to have a better chance of fitting you properly. Of course, Birkenstock fit and support can also be greatly affected by how snugly you fit the straps.
To check the width of a pair you already own, you can tell the fit by inspecting the footbed where there is a small image of a foot. If the foot is filled in, the shoe is a narrow fitting; if the foot is just an outline, it’s a regular fit. Also, all stock codes for narrow fittings end with 3.
Do Birkenstocks run big or small?
Most styles run true to size, the Gizeh and Mayari styles tend to run narrower than the others so you may be a regular in these sizes if you are usually narrow. Remember you want a little bit of room to allow your foot to move. The footbed is supposed to fit your foot but not be tight. Most people are a regular fitting, only if your foot moves side to side when you walk and adjusting the strap does not help that is when you would opt for a narrow fit.
How do Birkenstock fit?
The sandals are specially designed to support your foot with a firm and supported footbed, like a quality mattress they are not designed to be cushioned or soft. The moulded footbed has arch support, a deep heel cup and correct positioning which has plenty of room in the toe area. They are designed to make you distribute your weight evenly which helps posture and balance and gives you greater comfort when walking. To make sure they fit you correctly stand up in the sandals with the straps undone. Make sure your toes are not overlapping or rubbing and then fasten the straps of the sandals up accordingly.
What is the Birkenstock Footbed made from?
The Birkenstock footbed is made of resilient cork/latex and is shaped to create a healthy walking environment for your feet. Additionally, the cork/latex blend is pliable and reacts to natural body warmth. Therefore, over time, the footbed yields to your individual foot. Many long-term Birkenstock wearers find that the longer you wear them, the more comfortable they become.
