These are Birkenstock kids' sandals. I received them from a friend who said their child outgrew them after only wearing them once. However, they didn't fit my child either, so I'm selling them. They're in good condition and seem very comfortable due to their sturdy construction (as you'd expect from Birkenstock!). My friend only wore them outside once, and my child only tried them on indoors once, so I've selected "like new." As you can see in the pictures, there are no stains or marks. However, please understand that these are used items, so only consider purchasing them if you are okay with that.
