These worked out great for our 5 year old with flat feet - he absolutely loves them, says they are very comfortable and help him "run FAST!" The colors look super cute, I'm very pleased with the durability over several months (particularly, the hook & loop closure has held up better than other brands we've tried...), and they seem to offer great support while not being too heavy. Highly recommend, and will buy again.

Durable Shoes

Size: 3.5 Little Kid, Color: Blue/Black

Most brands have scuffed toe pads or poor quality Velcro. My boys go through 3-4 pairs of shoes a year. Our family loves saucony for the quality, comfort and durability.

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.
