These are Birkenstock Sydney Sandals in green and white. They are in excellent pre-owned condition. They are an EU 39 aka US size 8-8.5, and the last picture shows the footbed length measurement. The little picture of a foot on the insole surface is filled in, rather than an outline, which means the width is medium/narrow for this pair. Soft suede leather footbed, lightweight white EVA outsole, two adjustable straps with metal pin buckles.
