The BIRKENSTOCK Zurich combines the stability of an enclosed shoe with the lightness of a sandal and is popular in equal measure among both men and women. Although closed at the sides, this version is open at the toes and heel to ensure the feet get enough fresh air. Its natural design is down to the upper made from especially soft suede, which hugs the foot like a second skin. For 1/2 sizes, order next size up. N = Narrow Width.
