Made using an organic 90% Cotton rich yarn, these five toe ToeSox Casual Fishnet Full Toe Knee High Socks are woven in a diamond pattern pointelle style, softly lacy and breathable, with welt bands at the top and the ankle to keep the socks securely held along the leg. The seamless, toe-separating design allows a full and natural spread of the toes, correcting posture, strengthening foot muscles and increasing stability as you move. These ToeSox Casual Fishnet Full Toe Knee High Socks also have a woven-in arch band, providing gently supportive pressure to lift the mid-foot.
