Awesome socks, but the 3T looks like a baby sock.

Love these smart wool socks, just wish the sizing was more accurate. I thought I sized way up for my two year old's little feet, but after one washing the 3t is just barely big enough. Turns out the 3t is actually 2t-3t which is very different from just 3t. If I had known that, i would have gone with a larger size. They'll still get worn, just not for as long.

I bought these for my expecting baby and I LOVE them. Super cute

We just got 2 more pairs of these for our 3 year old. The 3T size is spot on, and still has some room to grow. We had some 24m pairs that finally gave out, but not after our daughter wore them for 2 years, and then another 2 on her little brother. They've got a good amount of stretch, so we expect these to last until our little guys is 4-5yrs old.

These are the most adorable socks ever! I bought them for my niece and they have been keeping her feet super warm and comfy. They are very soft and fit her little feet great.

I love Smartwool so I was thrilled to find that they carried toddler socks. I ordered the 24 month size for my 18 month old who is tiny and still wears 12 month size socks and size 4 shoes. These socks didn’t even come close to fitting him! The heel of the sock came to the arch of his foot! I would strongly suggest ordering waaaaay up.

I bought the 3T size for my 18m toddler who wears a size 6 shoe. WAY too small! Disappointing because I've always liked my smartwool socks.

I bought these for my one-year old nephew and they have to be the cutest little wool socks I’ve ever seen. The bottom of the socks was extra padded to keep those tiny feet comfortable. They have a good amount of stretch in them but they don’t get worn out and stay big. I love these and would definitely buy more.

We love SmartWool in our house. Definitely runs small, so I would size up. Our’s work just fine once we stretched them a bit.

I LOVE my smartwool socks, so I knew I had to get some for my niece when she came around. My sister loves them cause she knows my niece's feet are warm in quality wool socks!

Well made and my son seems to love them.

My son JUST turned two and it true to size in pretty much everything. We bought the 3T size as we saw it runs small, but they are WAY too small for his feet and now we can't size up as there aren't any bigger sizes! It's too bad as they look like great socks.

The Wife: I am a huge smartwool fan and love that they make them for our little ones little toes. If you love smartwool, you know that you are getting the best with this purchase.

These socks are so warm, but still thin enough to fit in sneakers. My 12-month-old has not had cold feet at the playground at 35 degrees with these. They are soft and comfortable, and I love the colors. As others have said, they definitely run small. The 24 month size should fit my baby perfectly through the winter, but he's he's a small child with only a size 3 shoe.

These are cozy and nice quality but the 3T is super small on my 2 year old. He wears a toddler size 8 shoe and the heel of these socks lands on his arch. I think he will be able to wear this month but not much beyond. I did notice on the size chart that kids XS fits 6-8.5 so if your kid wears a size in this range skip these.

These are great socks for the little one! As it turns to winter, we really needed something to keep our daughter playing outside even in the snow. She has very narrow feet and they fit great, despite other reviewers saying they fit small.

These are great socks, but like other reviewers have mentioned, they definitely run small. My 21-month-old is a size 5 shoe and I ordered the 3T, which fit perfectly (wouldn't want them ANY smaller)

I purchased these for a friend, who has a 1.5 year old. She said: "These socks are amazing! Not only do they keep our little girls toes dry and warm, they are so soft and don't seem scratchy like some wool garments. We have other Smartwool goodies for her and they hold up well and are very practical pieces that we will use again for our second child! We would highly recommend these and other Smartwool products for children!"

My son has problems with his feet being too sweaty and breaking out so we wanted to try wool socks. The socks (and leather shoes) helped clear his feet up immediately! They definitely run small and we will have to order a bigger size too soon but we will continue to order them.

These are thick, cozy, warm and dang cute. I've found getting winter socks from companies seasoned at making high quality socks (these are merino wool-sure to keep little feet warm, but still very soft) is much better than getting any ol' sock for cold weather. Great purchase again!
