Beige Birkenstock Arizona sandals, size 38, used condition. - Brand: Birkenstock - Model Name: Arizona - Size: 38 - Color: Beige - Sole Condition: Used Thank you for viewing. These are Birkenstock Arizona sandals, color beige. Unlike the regular ones, they have a glossy, enamel-like material, but it seems to be genuine leather. I bought them three years ago and wore them often, so they show signs of wear, but it's only on the soles, so it's not noticeable when worn. I usually wear 23.5-24cm shoes, and these fit perfectly.
