These are the only socks that I will wear on my job.  As a truck driver who unloads a tractor trailer full of groceries each night,  I'm on my feet a lot.  These socks fit great and allow my feet to breathe.  You can imagine how much they sweat with the strenuous work that I do!!!  I wear the long socks in the winter time and thought I would purchase these to try for the warmer weather.  They hold up and work just as good!  Will be buying more as needed.  Great product at a great price!!!
