I've worn these once but they felt so good I immediately bought a second pair while they were at such a great price. I looked at a bunch of pairs on amazon and was intimidated by the lack of sizing and M/F info, but they fit well and seem very solidly constructed.I'm a woman and wear a size 9.5 shoe usually. I've got average sized calfs. I ordered the medium size in purple and they fit great. Compression, but not cutting off my circulation. I will say I wish they were a half inch shorter, because when I sit they hit right where my knee bends.These are going to become a regular part of my running gear.⭐️⭐️⭐️⭐️⭐️'s, if only I had known to order up a size! It is a feat of unbelievable effort to get these on, usually too tired to pursue a rigorous run or brisk walk! But, they are absolutely amazing support!!!!I love these compression socks! It is amazing how much of a difference it makes when I use it during my walks or runs. I get shin splints when I don't use these compression socks, but when I do, I feel great during training and after training. I also watch for the sells here on Amazon and paying $19 for these... you can't beat that! ? I got the white ones on sale too! Awesomeness!!!I like the feeling of pressure, fit and elasticity.When I wear during exercise, I feel less fatigue and more strength, I am very satisfied and I am happy to experience good products.I always wear size 9 with Asics and size small of these socks is perfect for the foot part, but not long enough on the calves. (I'm 5'9'') The calf length of size medium with the foot part length of size small would be perfect. Still does the job.The socks fit properly as per size chart ( I got Small. I wear size 7 and have skinny ankles - 8"). The foot part of the sock was slightly too long for size 7, but it was not an issue. Good compression. Hold good after washing( I do not put them in the dryer). Would recommend.My husband loves this product as it provides great compressions for his feet at work where he stands for long hours! Be aware of the Left and right markings. He also wears the Copper-fit ones and he likes these better.I use this product while running. The socks fit well, I have womens size 6 feet and I am about 5 feet tall. The socks help my legs feel more comfortable while running longer distances.These are the first compression socks I've bought so I can't compare to others. They look nice and were comfortable until I went for a run in them. After only 2km my calf muscles felt like lead and ached - I had to go home & change into my normal running socks before I could complete my run. However I have found them really good for recovery after long runs (seem to have increased rate of recovery in calf muscles).Great fit and really comfortable. Good quality material. Works well to reduce injury and muscle fatigue.Classic compression leg wear. RecommendedComfortable and great on long runs for supporting the calf musclesIt's great ill advice my friends to buy it
