Thank you for viewing. Allbirds WOOL RUNNER MIZZLE Natural Black, 28cm. Purchased online last fall for 18,700 yen and used for one year. The exterior is in very good condition, but as you can see in the photos, the inside of the left heel and the insole have slightly deteriorated. However, they are still wearable, so I'd like to offer them at a low price to someone who wants to try Allbirds! There is some wear and tear, so I would appreciate your understanding of this being a used item. I may be able to offer a small discount if you leave a comment. Please feel free to ask if you have any questions. Thank you!
