    I bought these boots for my 7 year old daughter. She loves the colors, the ease of getting them on and how warm they are. They appear to be well made and should hold up for years to come.

    Great boot just hard to get on

    This boot is amazing for warmth and durability and I love how high up it goes. The only downside is it is really hard to get on. My 7 year old won't wear because she gets frustrated her foot won't go in. I even ordered a size larger but with the liner in it's just too hard to get on. So we have brand new boots that are amazing and my kids won't wear them. I'd still recommend this boot. I'm hoping we can break them in a little and they will have an easier time getting them on.

    My 5yr old loves his boots! They're very easy to put on; keep his feet very warm and they are light, which allows him to run and play, without feeling like he has rocks in his boots :) I love the removable liners. We like them so much that I just bough my 9yr old daughter the same pair.

    Awesome boots. They seem to run a bit small compared to the sandals. We had to send back and get a size larger than the sandals we ordered a month earlier. Happened with both kids. In short, great boot, bit get a size bigger than other keens.

    The ankle area is narrow and my child really had to push their foot into the boot to get them on. They also appear to run a bit small (length wise). I ordered a 9, the size of her shoes at home that she still has room to grow into. However, with the 9 Keen boot her toes were right near the tip of the boot. She did LOVE the look of the boot and I really appreciated the thick liner and ability to tighten the neck of the boot. We will order a larger size. Hopefully, the ankle area will be bigger; the boot was really hard to get on...that is my biggest complaint. I will update my post after I get the size 10.
