One month later - Pros & Cons
Size: 10 Little Kid, Color: Cobalt Blue, Size: 10 Little Kid, Color: Cobalt Blue
I purchased these shoes for my three year old son who is really hard on his shoes. I wanted shoes that were a good price value and that my son could put on and take off by himself, run around in, and that would stand up to 3 year old kid abuse. These shoes fit the bill, and for the price I would recommend them and I would buy them again, but they'd be even better if they were even more reinforced around the toes.
**This is NOT a paid or subsidized review. If you find this review helpful, please click "yes" - thank you!
PROS:
* Price - these are a well made, good looking shoe for a very fair price.
* Easy for my son to put on and take off, but do not fall off. Velcro is holding up well so far.
* The velcro tab that holds them on is big, so there's plenty of room for error in putting them on, and there's plenty of velcro to ensure a good hold.
* Nice looking - my son likes them which is a big deal when you're three.
* Stand up well to rough and tumble play
* Lightweight
* Good grip on the soles of the shoes.
* Fit is as expected, no discomfort, he wears them all day long without complaint.
CONS:
* As with all kids shoes, the toe area could be even more reinforced although he's worn them every day for a month and, as you can see in the pictures, they're not showing much wear.
* VERY lightweight - so if you're looking for a heavier, more protective shoe for any reason, this is not the pair for you.
Overall I'd highly recommend these shoes, and would purchase them again.

Easy 2-Velcro closure
Bought the first pair at Kohls, was a favorite easy velcro closure for our 2.5 yr old Grandaughter. Wanted pink and Amazon had these. Perfect fit one half size up. They run a little narrow and smaller but are lightweight and easy for a toddler to put their own shoes on! Her favorite.

run small.
Size: 7.5 Little Kid, Color: Peri
I was a fool and didn't size up, our daughter was only able to sue them for a minute. Should have sized up 2 sizes, I know better. A bit chunky too which I forgot about with these shoes, but fun color and easy to put on.

Stylish and comfortable
Great for my toddler, very easy for him to walk in. They’re sturdy but lightweight and have good traction so he doesn’t slip. He does have really fat feet so the Velcro is a little tight if you’re between sizes with a fat foot toddler size up
