Unsafe Buckle - Risky for tiny fingers
Special Size Type: Toddler (1-4 Years), Size: 12-18 Months Toddler, Color: Stuart Navy Canvas
I at first really liked these sandals, however once my son started learning how to undo the Velcro strap, his fingers began to catch painfully in the decorative buckle. Now I see the sandals as an unsafe option and have subsequently tossed them.

Cute but a little stiff
These are cute and well made. I think the sole is a little too stiff for babies learning how to walk that are used to bare feet. The back of the sandal also slips down sometimes. Overall a decent purchase if you just need something for looks more than function.

Amazing first shoes
Special Size Type: Toddler (1-4 Years), Size: 18-24 Months Toddler, Color: Matthew Navy
These are a fantastic in between option for after moccs and before hard sole shoes. Research shows that barefoot is best for foot development, but living in AZ the ground is way too hot for Moccs in the summer. These are a great compromise since we don’t want to use hard soles for as long as possible. Love this brand and these sandals are so cute!

Cute and Comfy
Special Size Type: Infant (0-12 Months), Size: 6-9 Months Infant, Color: Matthew Navy
My infant wore these for a few months, he’s 9 months now and they are too snug for 6-12 months size. We really liked the comfort and quality.
