The carefully designed compression provides support to your shins and calf muscles as you push them to the max, while the mesh venting ensures that you are not enjoying this support at the expense of hot, sweaty, overheated legs.

  • Built-in CW-X webbing supports your muscles and dampens vibrations
  • Mesh venting in key perspiration zones and moisture-wicking fabric keep you cool and comfortable

Here's what others have to say...


decent compression

  • Familiarity:I've used it several times
  • Fit:True to size

I have been having some calf cramps with bicycling. These sleeves offer a fair amount of compression and my cramping has lessened (who knows if it is the sleeves or something else). Sometimes I still use a "Ace" wrap because I can get it tighter. Next time I look for compression sleeves, I will look for more aggressive compression.


Great for soccer players too

    We bought these calf sleeves for my teenage son for playing soccer. He suffers from eczema on his shins and the guards always left his shins dry, burning and itchy. We tried some simple sleeves from a department store but it did little to help. After doing a little research, we decided on trying this particular sleeve and purchased a white pair. Since using these sleeves, he wears them under his guards, he has had no flare ups of eczema on his legs. He really likes using them and they do help keep his calves from feeling so fatigued after a soccer game. The sleeves are easy to clean. They can be hand washed or thrown in with cold water wash in the machine and then lay flat to dry. We will be purchasing more of these for seasons to come and they are definitely worth the money.
