Great shoe (but definitely runs large)!
Color: Reach for the Stars Cream, Size: 0-6 Months Infant
We love these shoes! Our very active little girl was getting blisters on her toes going barefoot, so we wanted some developmentally safe protection for her feet. Robeez shoes are backed by the American Podiatric Medical Association and fit the guidelines from the American Academy of Pediatrics. On top of that, these shoes are just a great product! They are easy for caregivers to put on, but difficult for babies to take off; the leather offers great grip and protection (no more blisters!), but are breathable enough to prevent sweaty feet; the top lip of the shoe doesn’t rub her ankle; the materials are quality (no staining/color transfer or weak stitches); and they are absolutely adorable to boot!! The only quibble I have is the innacurate sizing. The 0-6 month size I ordered fits my 10 month old’s feet perfectly. When I was shopping I measured her feet at 4.25-4.5 inches (11-11.5 cm), but ordered down a size based on reviews. I’m very glad I did! That small matter aside, I could not be more pleased with these little shoes!

Super cute
Color: Grey, Size: 12-18 Months Toddler
Super cute and so nice for when babies are first walking. They get softer every time baby wears them. Easy to put on and take off. Great quality and worth the price.

Perfect Soft Sole Shoes for New Walkers
Color: Briana Light Pink, Size: 12-18 Months Toddler
Robeez girl soft sole shoes are fantastic for new walkers. They’re lightweight, flexible, and fit snugly without slipping off. The soft soles provide just enough grip while allowing natural foot movement, which is important for developing balance and coordination. The cute designs are a bonus, making them easy to pair with any outfit. They’re easy to put on and stay comfortable throughout the day. Highly recommend for little ones just starting to walk!
