This is the Birkenstock classic model "BOSTON". It's made of oiled leather, which gains character the more you wear it. The soles show little wear, and the overall condition is good. There are some minor scuffs, but they don't affect wearability. Please check the images for the condition and purchase only if you understand that this is a used item. Please refrain from purchasing if you are overly concerned about details. No stains, tears, or odors.
