Looks great and are comfortable
Size: 6 Big Kid, Color: Black/White
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.

Great shoe seems supportive

Bought the shoe because it was recommended by a podiatrist for young kids and I'm pleased with what seems like good support.
