Hey OzBargain, I'm at the time of replacing my cheap socks for something a bit more durable. (Previously bought 1 pair poly black socks from Sunday markets and they haven't been very good. 50 cents a pair.)
Anywhere to go to get decent socks that last and more comfy??
Depends what kind of shoes you wear. I mostly wear steel cap boots, and then sneakers. For my steel cap boots I always wait for Woolies or Coles to go half price then buy Explorer Works socks. They are great. Comfy and well padded for work boots. For sneakers I normally buy Bonds socks when they are also half price (normally the same time as Explorer, as they are the same company) as they are also good quality and comfy. I only ever buy when half price though.
I used to buy socks form Kmart, but they die pretty fast and are too thin. Sometimes for certain items the cheapest option isn't always the best.
