If you are looking for indestructible socks then these are not for you. Those would probably have to be made almost entirely out of Twaron, Kevlar, Ballistic Nylon, and HDPE fibers - and they would cost as much as their weight in diamonds. But would probably not be very comfortable to wear on your feet.

I never owned anything from the Carhartt company/brand until 2012, when I needed work gloves for a specific purpose and the company I worked for had catalogs of this brand lying around. It is enough to say that I spent at least 50% of my work time then on my feet and would frequently end up in/near places where something was being built - and frequently had to wear steel toe shoes and other PPE(personal protective equipment). The usual "designer brands" are just not designed for that kind of work.

My problem has always been that my "designer" socks turn into rags within a month if I wear them all the time(especially when I wear them at work). So I had to buy dozens of pairs of those socks. The common problem is that a sock would get holes near the back(heel) of the sock and near the front(toes) because the fiber/fabric would wear away(layer by layer) too easily(and quickly) around those areas and eventually rip. Some have limited reinforcement near the front or the back but not over a large surface area.

The extra reinforcement of the above areas is why I bought these Carhartt Quarter Socks(and the similar and longer Carhartt Crew Work Socks).

The Positive:
+ I have used these socks since January 2018 and all are still intact.
+ I normally wear size 10.5 and 11 men's shoes, these socks(size "L" 6-12) feel neither too small nor too large even after being washed multiple times.
+ These socks are mostly made from cotton so I don't feel any irritation and my feet don't get too warm or sweaty(but it is still Winter in my area).
+ Comfortable to wear in cool temperatures but I wear longer socks for really cold freezing temperatures.

The Negative:
- The top stretch fabric portion(neck?) is not nearly as long as it is in the picture. So I don't wear Winter boots with these socks on. But this works better for warmer weather.
- Even after several months these socks still shed significant material(lint) on my feet.
- Feet/legs may get cold if temperatures drop below freezing.
- (For the nitpicker)The reinforced heel area could feel uncomfortable for some when standing up for a long time.

I have ordered more and I plan to wear these during the warmer/hot months of the year(the longer crew socks work better for boots and colder temperatures). I only bought the socks(black or grey) that have nylon reinforcement(I think simple polyester in the white socks will wear out faster). So far so good.
