Adorable but Run Very Small!
Size: 11 Little Kid, Color: Pearly Pink
These run very small. I was advised by my sister before ordering that Mini Melissa runs small; however, my daughter is a size 11 or 11.5 and since these run in whole sizes I couldn’t imagine ordering a 12! I would think a size 12 would be a range of shoe sizes 12 to 13. They arrived in time for an event we needed them for but were way too short in length so unfortunately they were returned. They are lovely, adorable, comfortable shoes but run very very small.

Cute and comfortable!
Size: 10 Toddler, Color: Mellow Rose
I’ve bought jelly shoes from other brands like GAP and Old Navy, but they hurt my girls’ feet. These ones are different, my girls love wearing them and haven’t complained about any pain and can walk in them all day. The velcro works well and easy to put on. The sizing is true to size. They can easily be rinse off when messy. The value for money is worth it and they appear to be durable.
