One thing you should know is that you will get a different reading on the size of your ankle depending on whether the ankle is flexed or not. I ordered an xl which turned out to be just a little loose, not enough compression. I emailed the company and they very quickly sent out the smaller size. The new size was in the mail in a day or two. To me that is great customer service.The sleeve itself is very well made and gives great support. Great product. Great Company.My feet wake me up at night. There is a very strong burning sensation in my feet at night. The first day I wore these socks for a couple of hours before bed and slept the night through. I put them one when I get home from work til bedtime and I have slept through the night ever since without burning feet. I don’t know how they work, but it is a relief to wear them.I did wake up one night with burning feet, put the socks on and slept with them on. That is how comfortable they are.I ordered size medium. My shoe size is 7 - 7.5.Ive been suffering from foot pain for several years now.I work in an industrial environment, and am required to wear safety shoes, which are far from comfortable. I have tried different socks, wearing no socks etc. There are times I can go days without issue, then simply putting my boots on, makes my feet scream in pain.Ive tried compression (full length), they seemed to help, but flare ups still occurred.I bought a pair of these socks simply because nothing else seemed to really work.I put them on when I wasn't experiencing any issues, so no news there.Then , I was sitting in my recliner watching tv and I could feel my left foot starting to flare up. I put these on, and the pain went away immediately!Its only been a few days, so I will update in a few weeks, but so far, i am impressed with the relief these socks give!I liked the sock. I use it at night when I go to sleep.Tight but easy to put on, relief of tingling and numbness quicklythey were really tight on the top of my the leg. I ordered the correct size for myself. going to give them to a 7 year old for gymnasticsI can’t say enough good about this product! I severely broke my ankle 3 months ago and am still experiencing pain and swelling. This sleeve puts just the right amount of pressure around my arch and across the ankle. This sleeve “hugs” my ankle area, giving relief and support. It is good quality. I’ve worn it steady for three days (off at night). I couldn’t wait to finish my shower and put it back on. However, they run small. I followed the guidelines for size women’s 8.5 foot and bought medium. It was like a tourniquet, so I returned to for a large. This is perfect. You get two, so I can wash one while wearing the other. I don’t know how it washes.Relief of all tingling and numbnessSizes stated are incorrect (product supplied was far too small). BEWARE the Money back guarantee - you pay return tracked shipping to Istanbul! A scam. Avoid!I purchased these compression socks for my elderly mother with the understanding that I would get a full refund if they were not satisfactory, they were too small. I ended up having to pay $20.00 to ship these back to the company which was not refunded.I ended up returning the socks. They were extremely painful and super hard to get them on and off (I was sweating ) !Maybe try to size up 2x it might work.I use this product for exercise walking sessions (45 - 60min walks). This product provides the compression that I wanted and needed, yet has remained comfortable (quality fabric that breathes, important in the tropical climate where I live). I find this product is good for light to moderate level activities.Large size was too small Used provided email to get in touch with customer support The resolution was quick and professional to my satisfaction I am impressed Recommend this product
