    Grand daughter likes them, she is 2 1/2 .win win!!
    Size: 7 Toddler, Color: Tan
    My grand daughter loves these shoes. She is 2 1/2. They are comfortable on her. Her favorite was the white 360 walking shoe but they unfortunately don’t make them in toddler size. (Hint: make them in larger sizes - and why not? ). So I got her these. Stride Rite are good, comfortable shoes for little ones.

    Could Be Better
    Size: 11 Little Kid, Color: Tan
    Look cute for a little while, then the toes peel as shown by other reviewers. It’s such a shame because my four year old LOVES the sparkly stars on the toes. I wish they made a more expensive version in a material that wouldn’t look worn so quickly.

    Great boots for fall and winter, but too short for deep snow.
    Size: 9 Toddler, Color: Navy
    This is the second round of these boots I bought for my kids. They are comfortable for all day at school, like sneakers. Perfect for wet days, feet stay dry and warm. They are not snow boots. We live in Boston and they are not for more than an inch or two of snow. I buy separate true snow boots for snow days (much warmer and taller boots).

    Perfect Winter Boots
    Size: 8 Toddler, Color: Navy
    I bought these for a trip to Iceland for my little one. They held up perfectly to lots of walking and playing! No break in period, and my little one was comfy the entire time! Warm happy feet is what you can expect with these boots!
