These are pre-loved in good condition. There are some signs of wear but the soles, straps and shoes have plenty of life left in them. The markings/stains are from my mom spilling something on them and they can probably be wiped down. Otherwise they have been well cared for. These are actually BROWN leather straps. These are a size 35 which is US size 4 through 4 1/2 per the Birkenstock sizing chart. My mom is usually a size 5 though.
