These Zensah socks are great. I have owned them for about a year, and just bought another pair since I have upped the frequency of my runs. Let's get right to what I like:1) NO BLISTERS. They prevent my feet from getting blisters on long runs (5+ miles)! Which is good. Because blisters are not fun.2) WARM. They keep my feet warm in subfreezing temperatures. I have run in temperatures as low as 7 Fahrenheit wearing these socks and running shoes. Running shoes are very thin, so I give a lot of credit to these socks!3) WICKS MOISTURE. My feet don't get really sweaty wearing these. Probably the cause of #1 (no blisters) but somehow it's like your feet barely sweat in most conditions. Everyone sweats differently. Your mileage may vary.4) MADE WITH DUMMIES LIKE ME IN MIND. You see that logo on the sock that is on the front, toward the top (knee)? That is not just for looks. It helps you put the sock on straight! You center that on your foot and on your leg as you pull it up. Which I always seem to have a hard time doing.5) SEXY-LOOKING. Yeah, I said it. They look nice. Dark color goes with everything! Makes my calves look beefy, too. So when people see me running, they are like, "Wow, that old fat slow guy has some beefy calves!"6) DURABLE. I probably have about a hundred runs on my first pair and I still use them. No holes, and I have razor-sharp toenails that love to make holes in socks. Big toe has this nail that kind of points up. It is really weird. And expensive due to constant sock replacement. But not with these Zensah socks!What's not to like:1) Not a huge color selection if you are the type of person to color coordinate with your head-band of the day or whatever.2) It takes some effort to put it on because they are tight. I have chronic back pain and the hardest part of a 9-mile run is getting dressed because frankly, some mornings, it hurts to put on these socks and my cold gear compression pants. But it is worth it, and now you know why because you first read all the many things I like about these.3) Someone said that these keep my legs from becoming fatigued. They may help a little, but don't expect miracles. They can't run the miles for you. You run the miles and your legs are going to feel it!Conclusion: I recommend these Zensah compression socks to anyone who runs for more than a couple miles at a time. Second most important piece of running equipment I purchased (#1 is running shoes).
