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.

If only the cosmetic laces would not break and fray.
Size: 6 Toddler, Color: Navy
As in other reviews I saw, the lace (cosmetic) on one broke off from the shoe after only a few times worn and so does not look nice. Frustrating because the shoes are great for walking/running/ playing. 🤷🏼‍♀️
