this size 13 stride rite boot has the exact same internal length as the stride rite size 12 1/2 made-to-play sneaker (that shes growing out of). the insoles are the exact same length. wont work. would have been perfect if it fit.

A solid, wide shoe
Size: 10 Toddler, Color: Navy
We struggle with finding wide shoes for my kids and Stride Rite is one I usually find myself coming back to. The price point is high but they are a good shoe. They are durable and long lasting. They were very comfortable. My son wore these for months until he grew out of them and we are saving them for the next kid. Highly recommend.

Happier feet for my toddler
Size: 8 Toddler, Color: Navy
My son was having some issues with a store brand shoes, I think his fit may have been a little too wide. It caused him enough pain he would take off his shoes. So I opted to invest in these Stride Rites. He doesn't want to use any other shoes. They are easy to get on, they fit him well. I like the fact that you can take out the inside of your child has wider feet. Instead of buying multiple cheaper shoes I'll just invest in a couple of stride rites if it means I have a happy toddler with happy feet.
