Adidas Flip flop slides

kids adidas flip flop slide sandals I didn't see a size on them but I am sure they would fit a 4-5 year old. my son is a size 1 now and they are too tight for him. so I would say these are a size 12/13. these are like new besides the dirt on the bottom of one from being worn in the back yard literally for 20min. color: black and white
