Double check sizing
Too big for my toddler, recommend sizing down. Quality is good if the fit is good.

Sizing
These were cute unfortunately way too big. The sizing thing is really off.

Yay!
My baby recently needed new socks, and I was looking based on three thing: - will they stay up - do they have traction - do they dig in and leave those awful red marks on him These socks not only have the stretch spot at the top like most socks, but they also have a stretchy spot at the ankle. So, yes, they stay on! Hallelujah! This also keeps them from digging in an extra lot at the top, so they're not messing up his circulation. The brand stamp on the bottom offers a little traction, but it's not exactly what I would call 'having traction.' Of course, most babies of my son's age don't actually need it, but I feel like that last little bit would take these socks over the top. Bonus - they're not cheap and falling apart, and they've got a nice knit to them. They're light. They're airy. They're great summer socks. They fit easily into soft shoes. Don't buy these as heavy winter socks. Heading into summer, though, I'm quite certain we'll be getting plenty of use out of these.
