Materials

Upper material: Natural leather The natural leather that we use is mostly smooth leather, in some cases tumbled leather. This type of leather has many special characteristics, such as breathability, adaptation to the shape of the foot and durability.
Insole: Natural leather Natural leather can be recognized by its untreated surface. BIRKENSTOCK purposely does not treat surface grains and other characteristic features. BIRKENSTOCK uses sturdy leather with a thickness of 2.8 to 3.2 millimeters as upper material.
Footbed material: Cork Cork is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning.
Outsole: Two-component sole The two-component sole combines the lightness and flexibility of EVA (ethylene vinyl acetate) with the elasticity and scuff resistance of rubber.

Widths: Regular vs. Narrow

Birkenstock styles come in two widths. Regular fits medium to wide feet (women's width equivalent C - D; men's D - EE). Narrow fits narrow to medium feet (women's width equivalent A - B; men's B - C) - the Narrow width fits most women's feet. Look for the footprint icon online and on the shoe box: an outlined footprint means Regular width, a filled footprint means Narrow width.

Testing the Fit

Before trying them on, flex the footbed by placing one hand under the toe and one under the heel - this begins the break-in period. Open all the straps, step in, then fasten them comfortably. Your toes should not touch the edge of the footbed; aim for about 1/4 inch of space around your foot. While breaking them in, keep the straps loose at first, wear them around the house for 1 - 2 hours at a time, and gradually increase wear time as the footbed molds to your feet.
