These soft and cozy tube socks are dyed by hand in Mira Blackman's backyard studio. Every element to the temperature that day to the way the wind is blowing affects the way they come out. It's a truly magical and collaborative process! 85% organic USA-grown cotton, 10% stretch nylon (outer foot), rubber core covered with nylon (inner top). Due to the handmade nature of this item, exact colors and patterns will vary. Fits women's sizes 7-11.
