Zoot has you covered.

By this point, we've all heard of the recovery advantages of compression technology, but what about the active advantages? Well, to answer this question, one only needs to try out the ZOOT Performance 2.0 CRx Compression Socks.

Compression socks are becoming an obvious addition to any endurance athlete's dresser drawer. After all, compression fabrics stabilize muscles in order to reduce damage during exercise. However, that's only one part of the compression story. These socks are made from ZOOT's innovative CRx compression fabric. Graduated in its design, the CRx fabric is made to compress the most at your foot and ease up as it gets closer to your calf. This forces blood flow from the bottom of your legs back to your heart. Essentially, this puts pressure on the muscles, arteries, and veins that are farthest away from the heart, ultimately forcing the body to circulate blood through narrower circulatory channels. So, almost like kinking a hose, it creates arterial pressure, and like when you finally release the kink, blood circulates faster to the heart. This accelerates recovery, by providing more oxygenated blood cells to the oxygen-deprived muscle groupings.

The "Y-shaped" heel construction ensures that the heel stays uniform with the rest of the sock as it compresses. The socks were finished with a compressive arch in order to support your foot during efforts. A breathable zone knit on the top of the foot also helps to wick moisture away from your skin to keep your feet dry, which minimizes the risk of blisters.

The Zoot Performance 2.0 CRx Compression Socks are available in the colors Black/graphite, Graphite/safety yellow, and White/black and in the sizes Three, Four, and Five. Please note that sizing is based upon calf circumference, so we recommend that you refer to the sizing chart. It's also important to note that these socks features an mmHg of 8-20, placing them near medical-grade compression. As such, it's not recommended that you wear these socks for extended periods of time.

Happy Feet!

  • Familiarity: I've put it through the wringer

These fit and feel great. Yet getting them on and off can be a challenge. They are thin. I have been skiing in a sock like this for the last 4 years and its made a big difference on my all day comfort. If you are having feet problems and spend to much time tinkering with getting you boots to feel better this is a great place to start.
