I ordered a few different styles of wool/wool blend socks and these were my favorite of the bunch. They were thinner than I was hoping them to be. My daughter complained of cold toes after wearing them on a ~30 degree day, so they are better suited to fall/spring temps. But they did have a warmer and softer feel to them than the others I tried.

These socks are awesome! I've found with past orders that Grodo socks run large, so got size 1/2 for our 2 year old daughter who wears a size 6 Softstar moccasin, for reference (roughly 14cm foot length). I tried size 3/4 for a few other Grodo socks and they were huge, like maybe will fit in 2 years. These are nice and thin but warm, and so soft! I wish they came in adult size. She wears them for sleeping under a wool fleece sleep sack. They've been worn almost every night for a few weeks and are holding up very well. Not too tight on the ankle either., but stay up nicely.

Really like these socks for winter wear. Go with one size up, as it runs slightly small
