I purchased these from Birkenstock. They have a zipper, making them easy to put on, and the inside is fluffy and very warm. They feel a little tight when worn with winter socks, but they're just right with regular socks because of the fluffiness. They are several years old, so there is some aging. Please refrain from purchasing if you are sensitive to this. The soles are hard, so I don't think they'll lose their shape much. The ribbon originally came attached to the right shoe only. Original price: 39,600 yen I have disposed of the original outer box, so I will ship them in a different shoe box. Thank you for your understanding. Color: Brown系 (Brown-based)
