Style and function A++++
Color: Love Bugs Taupe Leather, Size: 12-18 Months Toddler
These are the shoes every pre-walker, and early walker should wear. Foot protection, while properly developing muscles for balance. Robeez is the benchmark for baby shoes with style.

The leather material feels real and very soft
Size: 7 Toddler, Color: Black, Size: 7 Toddler, Color: Black
These are really nice baby boy shoes. At first i thought they looked weird but after you put them on, in my opinion they look quite stylish. My son walked with these for a while and did not seem in any discomfort or pain at all. The sole is nicely padded and the shoes are very easy to use and put on with just a simple Velcro strap. The fit is on point, not too large and not too tight either. The material seems like real leather material and its very soft and comfortable.
