They are full of European style, so they also work well as interior decor. Of course, they have excellent comfort, and because they are Birkenstocks, they are also great for foot and body health. Sizes available: 35→39. They will be shipped without a box, in simple packaging. If you need a box, it will be an additional ¥300.
