Hard to put on but easy to come off
Size: 12-18 Months Toddler, Color: Sebastian Shark Blue
As the title says, the shoes were a bit hard to put on and perhaps that was because we were doing it for the first time . However, they would come off super easily and so we lost one of the shoes the second time the baby wore them. That was a bummer as they aren't particularly inexpensive. We didn't really get to try them out as much as we'd have liked but based on what we saw, they looked comfortable and durable. Baby loved the shark design.

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.

Perfect shoes
They are so lovely and soft my granddaughter love them. Perfect size , so easy to put them on for the stretchability. I’m looking for a new pair in other color. 🥰
