Birkenstock Buckley Soft tones slip on clogs, women's size 42 EU or 11

Good overall condition pair of Birkenstock Buckley soft tones slip on clogs for women', size 11 US or 42 EU (see a Birkenstock size chart for more fitting instructions). These are a nice soft light blue color. There is a fair amount of dirt and dinge on each shoe. I have not attempted to clean. See photos for details and condition. Comes from a dog friendly home.
