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.
