Girls Sketchers Slip Ins little girl size 12 or 12.5

I *think* these are size 12 or 12.5 “little kid” (like a 6 year old). There are NO size stickers anywhere in this shoe. I compare it to a size 13 sketcher shoe in the last 2 photos. This might be either a 12 or a 12.5. The insoles do not come out. Smoke free home.
