2nd pair
Bought these locally for my grand-daughter. She wore them ALL the time and wore them out. She was so excited when I was able to find another pair on Amazon. She was begging me to sew them back together.

Defected Item
I bought two pair of these slippers, one for each of my children. One of the slippers on the smaller pair is defected, but alas we are past the return period. I just hate that we spent a good amount of money for what should be a quality product and it is defected. I hate for her to continue to wear them and possibly injure her foot due to the way the shoe leans.

Great quality
Size: 7-8 Toddler, Color: Moo-moo Cow
These are so cute and comfortable. My 3 yo can put them on himself and it is so cute that they light up. Fit as expected and are great quality. Even the dog hasn’t been able to tear them apart. Would buy more styles!
