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.

Great summer shoe for 8 month old.
Amazing fit for summer baby attire. Fits true to size, soft, easy on easy off. The Velcro is tearing up hos car seat though, because some rough surface is exposed.

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.
