Not stiff or tight…
Size: 13.5 Little Kid, Color: Turquoise/Multi
My niece loved them. So many of the slips in shoes are too stiff and tight, this one was easy on, not stiff or tight, just perfect!

Narrow
Size: 11.5 Little Kid, Color: Lavender
These were so cute, but run narrow. My daughter tried wearing them but she kept complaining they were too tight. Wish we could love them because I love how easy this brand is for my daughter to get on her feet
