The Birkenstock Kairo neon blue patent is a combination between a T-bar sandal and a normal sandal. The strap around the ankle is adjustable and made of Birko-Flor. The strap is finished with a patent layer to emphasize the colour. Of course, this T-bar sandal has the well-known anatomically shaped Birkenstock foot bed, with deep heel indentation and toe grip with a soft and moisture absorbent suede top layer. The Kairo neon blue patent is available in the width ‘normal’ in the size 35 – 39. There is also a sandal for children available.
