We bought these for our 10 months old... they are wayyyyyyy too big on her. They fit our friends 2 years old feet. I would say these work for kids wearing size 3-4-5 shoes. Ours is more 2-2.5
The quality seems good and the red one was pretty. The foot hole seems narrow enough to stay put.
We might reconsider next year.
I wish there was more neutral colors too.
