Socks can be rolled up to any leg length. ♥ Size 1 is shorter and measures 26.5 inches from the heel to the sock opening (30" maximum leg circumference!!). Great for skirts, if you have shorter legs, or don't want to roll them down! ♥ Size 2 is longer and measures 31 inches from the heel to the sock opening (30" maximum leg circumference!!) and is the size we recommend if you'd like to roll down your thigh highs.
