I love hanging out at work helping customers out, but after a while, sitting at a desk can takes its toll on my feet.
Sitting down disrupts the circulation to your legs, so sometimes it's nice to have a little extra help with the compression to keep the blood moving.
For a while, I even had a short bout with "chillblains", a medical condition that occurs when cold weather and poor circulation damage capillary beds in the skin(swollen, painfully itchy toes)
Wore these compression socks for a week and problem solved!
I wear a size 8.5/9 men's size, and the mediums were perfect.
Also, be sure to first bunch the sock up, and then slowly work the socks over your feet and up your leg to prevent the sock from ripping
