Pure wool socks are excellent for winter time - for indoor play and for layering underneath winter boots, wool socks keep little feet at just the right temperature, they breathe, and can simply be air dried between uses until they are soiled.
I love knit too, my slippers are now hand knitted from
pure Icelandic
wool, they are more like home
socks, I wear them all the time, super COOL, LOVE them....
