Cutest sandals for your little one (as long as they aren't learning to walk)
Size: 6 Toddler, Color: Brown/White
The sandals are adorable and great quality. However, when I showed the pediatrician before putting them on our 14 month old who is walking everywhere. She said "do not use" for children who are just learning to walk...these are great for those that aren't a "toddler" yet.

Size up for sure!
Size: 9 Toddler, Color: Matt Black
Bought these as a gift for my niece who wears a size 8 in toddlers. There is a note to size up from the seller but you may need to size up 3x. Ordered a 9 in the cozy jelly sandals, one size up as suggested & they were way too small. So I tried them on my other niece who is wearing a size 6 in toddlers & the 9 fit her perfect. She loved them & walked comfortably, she didn’t stomp as she usually does if the shoes are too heave or firm. & they have a nice sweet smell. I like that the Velcro straps adjust to fit her snug enough to hold her skinny foot in place. Definitely like the look, feel & quality. The sizing is really difficult to get right, I imaging depending on the style this may also differ.

So cute but runs very SMALL!
Size: 5 Toddler, Color: Brown/White, Size: 5 Toddler, Color: Brown/White
These are SO cute and smell so yummy however they run extremely SMALL! My daughter is a size 3.5-4c and j had read other reviews that they run small so I ordered her a size 5 thinking they’d fit perfect and they were still to small! Sending back and going to order a 6 instead in hopes that will fit because they are so cute and feel very comfy.

Disappointed
Size: 6 Toddler, Color: Pink/Glitter
Sandal is poorly designed. The sizing is completely inaccurate and the shoe fits awkwardly on the foot.
