There is a big difference between Birkenstocks Narrow and Regular Birkenstocks. The Narrow Birkenstocks have a narrower footbed than the Regular Birkenstocks, which makes them more comfortable to wear. They also have a slightly smaller toe box, making them better for people with narrower feet.
The Birkenstocks Regular are wider and more comfortable to wear, but they don’t have the narrow footbed of the Narrow Birkenstocks. The most notable feature of Birkenstocks is their footbed, which is made of foam rubber. The foam provides shock absorption and comfort when walking long distances.
