Held up for well for 5 months. Fit my son’s chubby feet like no other shoe.
My son has been wearing this shoe since he was 9 months old and was cruising furniture. I bought the 6-12 month size. He started walking at 10 months and is 14 months now. He’s still wearing this shoe and it has held up well. I have him barefoot in the house and mostly use it for when he’s in the back yard, at the gym childcare and when we are out and about. He wears shoes for several hours a day at least, though I bought the Robeez sandals at the start of summer and have been switching between the two pairs. My son has wide feet and doesn’t really fit in anything but soft sole shoes. His feet are about 5” long now and these shoes are getting too small. It’s almost time to size up! They’ve treated us well. Plus they are super cute and match every outfit. He giggles when I put them on.

Cute, different, and good quality
I had these for my kids when they were little. I am now buying them for my first grandchild. They appear to be the same good quality they were years ago. I highly recommend : )

Great shoes for the little one taking his/her first steps
Great shoes for the little one taking his/her first steps!! I actually ordered 2 pairs, one for my son in the 12-18 months (even tho he was 10 months old) and a 6-12 month for a friend. The 6-12 month fit my son perfect!! (my son was in a size 5) but I knew they would only last a few weeks so I kept the 12-18 month ones and he started wearing them. He seemed to like them, never tried taking them off and they were easier to walk in than socks but for some reason the top of the foot area is HUGE! They stayed on no problem but lots of wiggle room in the top... He is now running and wears shoes with a thicker sole for the rocks but we still love these for inside when it is too cold to go barefoot. I would say the 12-18 month fit like an average size 6.

Great barefoot option for early walkers!
Size: 12-18 Months Infant, Color: Grey
A moccasin is such a great place to start! Buying barefoot shoes can be hard.. they’re not always the cutest, can be expensive & there’s a lot to pay attention to! We love moccasins as a great first shoe for our boys. Perfect for summer because they’re more like a sandal & let in air flow. Why we love: ✨Meets barefoot-style checklist ✨SUPER inexpensive ✨Quality made & last a long time ✨Lots of style & sizing options ✨Breathable ✨Easy to put on & take off ✨They protect feet all while still giving a sensory experience These ones do run big, so size down. If you’re looking for a shoe that has more grip on the bottom, there are tons of moccasin style shoes with grip as well. Give these a shot if you have a fresh walker on your hands!

Great shoes for first time walkers!
Size: 12-18 Months Infant, Color: Grey, Size: 12-18 Months Infant, Color: Grey
The material is great! My child likes it and hasn’t tried to take them off! They are lightweight and not bulky. Very flexible ! Also I did my research and it’s made in the UK and made with genuine leather! The color is cute as well! Wish they did have more variety here in Amazon but still okay with it!
