I'm selling a pair of Allbirds Tree Runners, size M9 (approximately 27cm). I usually wear 26.5-27cm. They show signs of wear, but are still wearable. The soles still have tread (as shown in the photos). How about them as a spare pair? *Please note: They will be shipped without the original box, and they are not new. There is a used feel, so please refrain from purchasing if you are sensitive to this.* Size...26.5cm Size...27cm #Allbirds #Sneakers #Spare #27cm #26.5cm #TreeRunners
