I bought the swivel cuffs because the elastic on the leg socks was so tight it cut into her ankles and left lines, but they don't get much better. I understand you don't want baby socks falling off, but the area just above the ankle isn't very flexible so it fits very snugly around my granddaughter's ankles. If they shrink in the wash, they may be too tight. I don't know why they can't add more "compliance" to the elasticity.
