These Bonn Birkenstock clogs have been well used. I have had them for years, and I'm finally ready to let them go. Please take a look at all of the photos. The leather upper is in excellent condition. I have regularly cleaned and oiled them. The cork is a bit worn on the heels where it connects to the leather. The outsoles are very worn on the heels. Because the leather is in such great condition, these could easily be resoled and have many, many more years of wear.
