The NZ ones are different, at least the ones I got were. Warmer and less breathable.

I treat them as a disposable item I replace every six months you can spend more Monday and maybe they will last 12 - 18 but meh you are wearing them 5 days a week, they are going to wear out and are cheap

 

I agree. I buy mine from the local dollar store, 3 pairs for $25. I hate socks with tight tops, and the ones I buy are "diabetic" socks (I am not). Never seen this option with standard socks from standard places. They only get holes if I am slack on cutting my toenails.

I wear what i think are darn tough T4021, mine have Z4021 on them. I wear them for about 12-14h a day 48 weeks a year with my work boots. I recently threw a pair out that was 4 years old as it had a hole where you pull them up near the top. 

They are a medium thickness, comfy and wick the sweat away from your feet. i currently have 4 pairs in rotation so each is being worn about 2x a week so about 90-100 times a year. Washed and dried in a dryer with poor temperature control. About 15% of the time they will be hung out to dry.

Best work socks ive had. 

I also wear them with my footy boots for the kids games on the weekends.

If you only get 10-15 uses out of your socks you either have calloused up feet, ill fitting shoes or something else causing them rub in ways they are not designed to.

Where do you get these from? I'm assuming these aren't The Warehouse ones?

Nope not warehouse ones they all seem to be at least 1/2 the price of the ones i have. 

Work obtains and pays for my socks and footware.
