The Women’s SMARTWOOL ARROW DREAMER Mid Crew Sock. The women’s specific fit is slim with a narrow heel for added comfort and support. Ultra light cushioning under the foot provides cushioning without adding bulk. Merino wool is breathable and stays dry while regulating body temperature, so your feet stay comfortable no matter how active your day is. The supportive arch brace keeps the sock on snug and secure. The virtually seamless toe uses minimal stitching, so there’s no excess fabric. The mid crew sits right above the ankle.
