Used shoes
Size: 10 Little Kid, Color: Glitter Clear W/Strap, Size: 10 Little Kid, Color: Glitter Clear W/Strap
If I could give this zero stars, I absolutely would. I ordered these shoes expecting them to be brand new since I paid full price and never selected any “used” option. What I received instead were clearly heavily worn shoes there were visible signs of use that you simply wouldn’t expect from a new product.

Pricey but worth it
To say my daughter loves shoes would be an understatement and whenever you throw in a fun color and glitter to the mix, it only exponentially increases the love and excitement every time she puts on these shoes! The quality of the shoes are outstanding, they provide support in the right places and so far have been surprisingly durable (for a toddler that’s saying something)! This is the second pair of this shoe that I’ve purchased, the first was a pair of the clear glitter style. They are very cute shoes and the color matched the pictured on the website very well, which was great since I was trying to complete a “Princess Anna” look with a previously purchased dress. Note: I do suggest to size up one size, because in my experience they run a little small.
