Way too big
Size: 6-9 Months Infant, Color: Mariposa White Leather
Adorable but sizing is WAY off. These are massive and look like toddler shoes on our (tall and bigger footed) 7 month old.

Cute but flimsy soles
Size: 9-12 Months Infant, Color: Mariposa Light Pink Leather, Size: 9-12 Months Infant, Color: Mariposa Light Pink Leather
I wanted to love these because they're the few leather options out there. Unfortunately, the soles are made of a flimsy material that came apart after less than 2 weeks of wear. Not sure how long they'll last...

Fits like a sock
We bought these for the Florida beaches, not knowing whether our beach would have debris, shells, or the common straw sticking up to assault your feet! We bought them for our one year old and she loved them. The sole is thin and moveable, but still protected her feet. Our beach ended up being pristine and clean, so she didn’t really need them. We let her wear them at home in the grass because she was that obsessed with them. Nice product and we’d buy them again, if needed!

Favorite Robezz shoe style
These are great, flexible sole that is a step up from the leather soles. This is a rubber gripper sole that protects the foot but gives great moment for new walkers! The fabric was better in person than I expected.
