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!

Cute but not totally practical
Size: 13 Little Kid, Color: Navy
These are cute and decent quality but they are so short they aren’t practical if you live where there is snow. Deep snow just ends up in the boot. Great for cold but no snow or slightly wet and muddy days.
