I've never before purchased any product with 'copper' as an ingredient. Of all the compression stockings I've used since my foot surgery, which there have been many, this particular product was the best fitting and the most comfortable. At no time during the day did I have to readjust these stockings. Additionally, they were so comfortable I did not even know they were on, nor did I feel any discomfort in my foot or leg. I would definitely recommend this stocking!
