Good Luck Sock's Active Fit socks are made of combed cotton with reinforced heel and toe, and mesh vents. The Active Fit socks also have a deep heel pocket and an elastic arch band. The designs are sublimated into the fibres of the sock, and won't lose their colour. They're thicker than Good Luck Sock's Crew Socks, and are great for whatever your day has in store for your feet.
