I don't know if zappos carries the Sonnet brand (they're also sometimes referred to as Start-Rite, I think), but they have really adorable shoes. There are some shoes stores in NYC that carry them, but I'll bet you can get them on line. They have buckles (no velcro -- I couldn't tell if velcro was a plus or a minus for you) and come in small sizes.
ETA: Zappos does carry a few styles. The
Delphine are really cute. As are the ones with the crepe soles, though I couldn't tell from the pictures whether this site carries them.
