These are Birkenstock Super Birki sandals that I bought three years ago. They have the nostalgic insole, and it's a rare model that's no longer sold. I've used them many times, so there are scratches and dirt. The insole is also peeling and worn out, so I'm selling them at a low price! Please refrain from purchasing if you are concerned. m(_ _)m #Birkenstock #Birkenstock #Birki #SuperBirki
