I bought these because I have begun walking/jogging again but have been getting shin splints and some problems with fatigue in my lower legs. Doctor recommended trying compression socks to help aleviate the problems and I have to say it does help a lot. Wore these during a 5 mile walk/jog and had no problems with my shins or feet at all. Wore them for a few hours after the exercise and it helped even more. Good product and I would recommend these for anyone who has problems with their lower legs during exercise. Also, the fit was good. I wear a size 9 womens and the medium fit perfectly as the website recommends (go to the cw-x.com website for sizing guides).
