My toddlers and I LOVE these socks! They are size 10 and 11.5 in shoes and the large fits great. Can’t comment on longevity yet but they seem to be made well.My son loves trains, cars, planes, so these were a first pick when he needed new socks. He is 4 yrs old, but i got the 5-7 age pack. They fit him well, are very stretchy and are pretty thin. Didnt seem to shrink in the wash/dryer, always a plus.I’d say they could use a bit more padding in the heel and toe area for the longevity of kid socks. I’d also like to note, that the colors and patterns are mildly reminiscent of an older man’s golfing socks.My next sock buying option might have more material to withstand the abuse they take from their wearers.I got these for my 10 year old who wears a size 4 on big kids. I got him the size for 9-12 year olds and I have to say, they almost don't fit him. They fit for at this moment but won't for very long. They're on the thinner side which wasn't a problem for us but may be for someone else. And the color great overall I give it four stars though I do think they run slightly small as my kid isn't a huge kidTo preface, my toddler has chunky feet, so they were a tad bit tight. Otherwise nice socks, they do well in the wash. I would say that if you have kids with normal feet, they will fit just fine.The socks are on the cheaper side, they're equivalent to dollar tree ones. They're soft and have nice stretch, but they're thin.I'm not in love with the dull coloring of these socks, but my daughter is very active so colors don't matter to her. These socks are a good fit with about an inch of growing room. Unfortunately, these do not have the no-skid bottoms, so you might want to get these for well walking toddlers before purchasing.I got these for my daughter and son, I got the pack of 12 which I awesome I love buying in bulk when I can, especially socks Lord knows we go through them lol. They are comfy but are thin but they like that, it doesn't sweat your foot great for summer wear for when you have to wear shoes. We like them and recommend, but I think it's just a bit pricey, I would lower the cost them being just plain regular socks!My daughter is very specific with what she wears because if it’s not comfortable she will not wear it and she will throw a fit. ? so I am here to report these socks are a super comfortable material! I’ve washed and dried a few times and they haven’t shrunk or change shape, which is excellent! They come up right above the ankle, so great for the season of little booties ? Also a good staple piece in your kiddos wardrobe. We have lots of colorful mismatching socks so it’s nice to have good basic colors. :)
