Working in the lab, standing for hours is a considerable burden to even the very-well-trained lean legs I have. A nurse friend of mine recommended getting compression socks that are a must item for nurses. I never tried them before, and when I searched compression socks on Amazon, there are so many different kinds and of different brands. I gave socks n socks a try because I liked the designs. The shipping was fast, and each 5-pairs ( I bought 2 sets of 5 pairs) came in a neat package. The quality is great, and they fit perfectly. I walk around for hours and hours at work and ride a bicycle, but the socks remain knee high and do not come down, giving a steady good pressure to my legs. I have been wearing them every day to work and absolutely love my socks. The colors are bright and haven't faded after washed many times in a heavy-duty warm-water cycle.
