Air Loubis

Has anyone pulled the trigger and bought these? I saw them in person and they are adorable, but the fact that they're meant for indoors discourages me from buying. If anyone has purchased, did you wear them outdoors? How did they withstand?
 
I think I may take the plunge. I work in a law office with all carpet floors so I think these would be adorable for around the office! I usually wear flip flops or rain boots in to work in the winter because city streets are usually pretty gross then and I don't want to ruin my good shoes. I would never use them for just slippers but I think these are really adorable for work. Maybe I can try to hunt down the black around my area!
