Beautiful rust color nubuck leather Birkenstock calls pecan. Goes with everything! I bought these in April 2023 and wore infrequently for about 3 months. Excellent condition, you can see the leather foot bed is just starting to darken from wear, which happens with these type sandals. I love them, and get lots of compliments on them! Very comfortable for walking. I’m transitioning to barefoot shoes which is the only reason I’m letting go of these now. Size 36 which corresponds to a US 6.
