Great shoes
Great shoes, but definitely designed for narrow feet! if your child has wide feet,i recommend choosing a different style as these run very, very narrow.

Great colors!! Love the soles are not white. Good price
Size: 10.5 Big Kid, Color: Navy/Citron
Held up better than expected. So far only keens had held up to my son's play. Update-- after 2 months of wear the sole began to peel off/separate at the front of toe of shoe where that " upwards tab" is located.

Saucony!
Size: 13 Little Kid, Color: Blue/Black
Saucony has saved me more times than I csn remember! The price point is always affordable and I’ve been buying this brand for our family …toddler through our adult sizes! These shoes usually last one year for an active child but that shows they wear them all the time. This style is adorable and our son was so proud to open the box and wear them. We’ve worn this style everywhere… fair 5ks, trail runs, bike rides, city shopping trips… and they always look great and are an easy Velcro shoe for a child.
