Good - but not really wide
Size: 2.5 Wide Big Kid, Color: Black/White
I purchased these for my son (6 Years old). He has quite a wide foot, so we purchased these because they said they were wide. They were not. Overall the style is nice, but in the end we had to return them and we wound up with some Sketchers wide sneakers that truly were wide.

Love them!
Size: 4 Wide Big Kid, Color: Black/White
Great quality, fit as expected, comfortable, and a great value for the money! I wear a size 4 widechildren’s shoe, which makes it very hard to find footwear that fits. And these fit just right!

Great shoes with a durable design. Upper mesh upper is breathable, they are stylish and very comfortable. My son loves it and it has become his favorite since the day he started wearing it.

Light, comfy, and a brand you can trust with your feet
Size: 3.5 Big Kid, Color: Black/White
My son tears through shoes and somehow they're perpetually untied, no matter what we do. These are great as they don't need to be tied but look laced up, are very light and cushiony, and just look great so they go with everything. Saucony is also a great trusted brand that I've run a few marathons in myself, so I figured, let's try a pair and see how long they last. It's only been a few days but I'm getting good reviews from my son and they're his new go to pair.
