Question: I want to buy one for my husband. I would like to know how the sizes run.
Document: I decided to try these compression sleeves a couple of months ago and like very much. I don't know if they do every thing that they are hyped to do but they are very comfortable. I was a long time runner but as I've gotten older I no long run but rather walk between 5 and 10 miles a day. If I know that I am going to go on long walk I always wear these sleeves.
I have a pair of Zensa's also but I prefer these. A little longer, a little more snug and lighter fabric. Both great products, but my choice would be these if/when I buy again.
This is my 3rd pair of CEP calf sleeves and so I knew what I was looking for and knew that this brand was the one to buy; no need to look around.Very comfortable, very tight and very high quality.You get what you pay for that is for sure.
I've been battling some major shins splits while training for triathlons. I started wearing these when my shin splits were at their worst. After a few of my first runs when wearing these i noticed a huge difference. I wear these every time i run, even if its only like a 5k. I continue to wear them after I run for about an hour as a method of recovery. I love these, I have to pairs and rotate the colors.
I ran(slowly) my first marathon in these. I get a lot of lower leg pain in both legs at the beginning of my runs. These seem to help more than the compression sleeves that don't look like socks. There are lot of products for running and I can't say for certain if these will help beyond a placebo effect, but I'm going to keep using them.
I've used these for cramping in my calves and they completely alleviated the cramping issues that I had while running and using the elliptical. The quality of the material and fit have withstood several washings.I would recommend the CEP brand OVER the 2XU which started to rip at the seams/stitching after a couple wearings.
I can't say how well these particular braces would fit someone over six feet with very long legs, but certainly far better than cheaper, lower quality braces which are far shorter.Note that these braces are advertised to fit calves size 12.5 to 15 inches.
Wish they made these in a longer size. The color is great and my husband wears them on the golf course but they slide down. Could be made tighter and longer.
This is the only brand of compression sleeve I wear. I did get the first pair at a running store so I could be fit for my size. They are cheaper here and there are more color options. These fit great and really last. I have friends that have issues with other brands not fitting properly. I have not heard of anyone having an issue with the CEP brand. I would never waste my money on cheaper brands.
I have had a recurring knot in my upper calf. The support given by these sleeves have let me run without cramping up.
