After years of looking, I've found the perfect sock! This sock is midweight on the sole, up the sides, around the toes, and around the heel. The top of the foot and from the ankle upwards are thinner. The sock stays up and wears and washes well. There is extra support around the middle of the foot, but the toe area is loose - a real boon if you have toebox issues such as arthritis and don't like it tight there (I wear a size 8 shoe). Purchased it in all available colors, and will be back for more. Wearing some now, out for a spring hike!
