Great for toddler
Size: 8 Toddler, Color: Grey
My toddler felt these comfortable. He was able to run with support, and material was great. These do not tear easily.

Perfect footwear! Wow...
Size: 9 Toddler, Color: Navy
Stride Rite deserves all the hype... The best children's shoes we have ever owned. I love the removable insert that lets you measure the foot, or adapt for wide / narrow feet. We took it out just to prevent extra pressure on the bone structure.
Basically, I bought one pair of these, and one lower quality brand just for playtime / getting dirty, etc. It was a great setup and it's nice to have two pairs of shoes available.
He outgrew these and I got the next size up of the same style. That's a very good sign 👍

Great fit and protection
Size: 4 Toddler, Color: Champagne
We live in San Diego and don't really need warm, waterproof boots most of the time. So when winter started and my daughter had just started walking, I decided to get these as an additional shoe to her stride rite sneakers. They fit really well on my daughter's wide, chubby foot, which is my number one priority.... No other boot we've tried has made it past her toes. I like that these aren't too warm inside, and just have enough fur to keep her legs warm. They fit great over jeans, tights, and thicker socks. And as with all stride rite sneakers, they're incredibly durable and stylish. A bonus that I can take out the padding for my daughter's extra wide feet.
