At first l hesitated to order, because of some reviews. But these socks are made well, the material is thick, and they DON'T slide or roll down. The color of them is little on yellowish side, and some are little tighter fit than others. I match up loser fitting ones and tighter fitting ones, separating them. With 8 pair you can do that. The difference is not very noticeable. This was a good buy and l recommend them. One advice: if your size is borderline between the two offered sizes, order smaller one, it definitely holds up.I love these socks. I recently started a job in healthcare 3rd shift after almost 6 years of not working. The first 2 or 3 weeks I wore normal socks because I hadn't got paid. As soon as I did, I bought these socks and let me inform you. It was an absolute lifesaver and game changer for my feet and legs. I was coming home every day in so much pain in my feet and legs I couldnt even stop moving them. These socks are amazing. I highly recommend them, as a matter of fact I'm probably going to buy a second set.I got the L/XL as my calves are pretty wide because I'm plus size.First day helped swelling go down!!!I checked with Amazon before I went to my local store and comparedprices. WOW, I got more than I needed but at least I did not have towash them every night, and I gave a pair to my Dr. to give to someone elsewho needed them. GREAT VALUE?Love the comfort, my calves are not achy after a long standing day at work. Good quality, great price! Fit to size! I bought a second set!Doctor said it might be good to start wearing these types socks. I especially like the color assortment.These are what they are 15-20mmHg and work fine, they definitely stay up in place but also a 15-20mmHg isn't really tight in the first place.These socks are ok but they fit too tight for me. I ordered the same size I always do but they’re too uncomfortable for meMy husband wears these to work everyday. They help keep the swelling down.Los calcetines me quedaron muy bien en cuanto a tamaño, la tela se ve de buena calidad, lo único por lo que no le doy las 5 estrellas, es que se supone que son de compresión 15 - 20 mmHg y siento que NO son de esa compresión, yo uso otros calcetines para mi día a día y son de la compresión 15 - 20 mmHg aprietan un poco más. Estos como son blancos los compré para hacer ejercicio.Only had a few occasions to try these socks out and they worked very well. The quality of the material is very thick and decent. They seem tight all the way up to my knee which I assume are doing the compression thing. My regular socks were leaving deep indented elastic marks around my shins due to being over weight, but after shedding 20kg , there were still marks. These socks have eliminated any of these pressure points and even under the knee where they end is not indented. 8 pairs of quality work socks will last me a long time.These are not compression socks. They weren't even comparable to crew socks. Socks were extremely loose (think 80's girl anime socks) and so not worth the money. I returned them.Mi esposa está encantada, le han ayudado mucho para proteger sus piernasHago guardias de 12 horas en un hospital y paso mucho tiempo parado o caminando.
