  • Very cute but for narrow feet

    These are very cute and different shoes so it's disappointing I couldn't even get them on my daughters wide feet. I even bought a size up :( I really wish they would have some kind of narrow/wide fit description for each shoe. I normally buy the Newport's for my son extra wide feet. I guess I just assumed these would be wide too.

    Probably can find something better...

    Still a bit tight even though I returned and ordered a bigger pair. Both pairs took longer than the original date stated to get to me. Still waiting on my refund for the first pair. Cool looking shoe and light weight. Also fit a bit small.

    I will most definitely purchase again

    The perfect summer shoe for on non-stop 4 1/2 year old grand son. He loves the colors and they are easy for him to put on and take off, yet they endure his jumping, hopping, and running.

    the boy loves 'em

    Bought them to use as winter house slippers up here in Alaska, he thought they looked super cool. Now that things are thawing out, I'm sure they'll make their way outside for running around (until he grows out of them!) Size runs true to other kids Keens

    My son loves these shoes! We live in Florida and they are the best combination of tennis shoes while being light and airy. And he can easily put them on and off.

    Nice, and appear to be great quality.

    Kid loves them. Just received them, but so far, so good.

    Love this style of shoes for summer. I wear a small size and hard to fit. This style fits so good and comfortable. I bought my first last year and loved them so much, I bought 3 more this spring!!
