Foot circumference 37.5 (40, 45, 50, 52.5, 55) cm approx.
Leg and foot length adjustable.
These socks come in 5 sizes from baby to adult L. They're knit from the cuff down with a slipped stitch heel flap for extra wear and a wedge toe.
The i-cord tie is designed to keep the socks on wriggly baby and toddler toes but are optional for all sizes.
Any worsted/aran weight yarn knit to gauge is suitable, however, I would recommend using a yarn with some acrylic/nylon content, especially on the bigger sizes, to allow them to be hard wearing.
