Vibrant and Comfortable
Size: 5 Big Kid, Color: Lavender/Multi, Size: 5 Big Kid, Color: Lavender/Multi
When you have kids, you KNOW how hard it is to get them out of the house! We got these for our daughter and she grew out of them so quickly, (As kids do) but she loved them SO much she just wanted the same shoes in the next size so that’s exactly what we did.
She can slip her feet in them SO easily. They have good arch support and they are comfortable enough for her to walk all day at the parks and they are easy to chuck in the washer and dryer to clean them. Unless they change the quality or durability, we will continue to purchase this brand for both ourselves and our kids!

Daughter’s Fav.
Size: 6 Big Kid, Color: Lavender/Multi
These are my preteen daughter’s favorite shoes! She likes that they slip on quickly for those times we are running late. They were comfortable throughout the day during our trip to an amusement park and we walked a lot! They are holding up well and look cute- even after washing!
