BIRKENSTOCK Birkenstock Boston 37 Oiled Leather Soft Footbed Purchased at a domestic department store. Used about twice on the home terrace and then stored. Soft Footbed The soft footbed has a built-in foam rubber insole, making it more elastic and gently conforming to the foot with its cushioning. Recommended for those who prefer a slightly softer feel than Birkenstock's original footbed. Because it is thicker than the original footbed, it may feel tight if you choose the same size as your footwear with the original footbed. Due to the characteristics of the oiled leather material, there are scratches and marks from the beginning. Also, the color may appear different depending on the environment. The actual color may differ from the images. Please refrain from purchasing if you are concerned about minor details. Please feel free to ask if you have any questions. Thank you for your continued support. Size...23.5～24cm
