The matte Birkenstock Boston is made of oiled black leather and is the eye catcher of the Boston collection. The matte leather gives this mule an industrial look. Above the instep a strap is attached to adjust the mule to your foot. This luxurious mule can be used both inside the house as well as outside. The anatomically shaped Birkenstock foot bed with deep heel indentation and toe grip ensures the most optimal support of your feet. The soft suede top layer on the foot bed makes it feel warm and soft. The Birkenstock Boston black oiled leather is available in the width ‘broad and normal’.
