The classic ribbed plain possum merino sock. Hard working, ultra warm. Nothing else to compare in the market place. Suitable for those who suffer bad circulation if the skin is un blemished and not showing signs of damage. A must for the winter season and ideal as a bed sock. Also can be worn for at least a week, and no smell no sweat.. a remarkable sock. truth be told, many people admit to wearing up to four weeks, and still seem fresh and clean. I can vouch for that myself. Not recommended for wellington boot or work boot, more suited to standard shoe. If you are type 2 daibetic and require a soft top, low tension seamless sock, please see the other health sock available on this page. We have a plain dress sock and a health sock.
