I got these for my daughter when she was 1.5 yrs old, they stayed on well and fit for quite a long time. She loves how they light up and the nonskid allows her to run run run with no slipping! They also hold up really well! My younger daughter will be able to use them when she gets older. We love them so much that I just ordered the next size up for my now-three yr old big girl!

Pros: Quality product will last long enough for hand me downs.
Fits well thru multiple sizes
Nonskid works
LED us bright and kids love it
Super cute
Soft sole is ideal for foot development

Cons:
Can get dusty quickly due to fuzzy "bunny fur" fabric.
Will not survive if you let them go outside, definitely indoor only!
