Now that I've determined trampled for over 10 years my last pair of slippers was time to an AC. In slippers a course Birkenstock think of always the same. Thus, I've looked at the different models and I ended up relatively quickly in this model. Although my wife claims that would be "Grandpa shoes", I will not get myself small. The shoes are super comfortable, and especially in this cold season very warm. Visually, the workmanship is very good and the materials seem to have a very good quality. We will see how the shoes now prove over the years.
