These are incredible - they last FOREVER. They are soft and wonderfully breathable. one pair usually lasts a year. towards the end of the winter/spring I check the heels - the ones that are showing shoe nubby pulls, I will cut the legs off a little above the knee. I then have a control top that I can use for the summer and have bare, cool legs - this is great - no runs, no frays, no roll up. Did I say amazing. For care - throw them in the washing machine, gentle cycle, then to the dryer or air dry - even the half legs pairs. life is so much simplier. Sometimes I like a more sheer hose but that was mostly in the summer and now with the half leg hose - good to go!!!
