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.

Slip free bottom and Durable!
Size: 12-18 Months Toddler, Color: Sebastian Shark Blue, Size: 12-18 Months Toddler, Color: Sebastian Shark Blue
These are very durable and have the flexibility for your little ones foot to grow as it should! They provide elastic-like material around the ankle for easy on & off, have a slip-free bottom, and are soft and cozy. These come in many different designs as well, I would say these are definitely worth the money! Plus, super cute!!
