Born to run.
The culmination of years of field testing, prototypes, and running experience, the PhD Run Light Elite Pattern Micro Socks are Smartwool's most advanced run socks yet. Merino wool offers unparalleled temperature regulation to help your feet stay cool from start to finish, and the 4 Degree Elite Fit System offers excellent stretch and recovery so your socks don't slip or bunch halfway through your run. Mesh venting offers relief on hot weather jaunts, and Light Elite cushioning offers targeted impact protection at the ball and heel of the foot to elevate comfort with minimal in-shoe volume. And with durable Indestructawool technology, these socks are built to go the extra mile.

- Q & A
Perfect low-cut sock!
- Familiarity: I've used it several times
This sock rocks! I love the comfort and thickness, plus the merino wool doesn't smell at the end of a long day! I love the tab on the back that makes it almost impossible for the sock to ride down.
Cool and Light
- Familiarity: I've put it through the wringer
I really like these socks. They are thin, keep my feet cool and dry, the material is comfortable, and they have cool patterns.

Wearing these right now
- Familiarity: I've used it once or twice and have initial impressions
So far so good. They don't feel different than other sport socks I've worn, but that's not a bad thing. They fit and feel great. If these survive the test of time and the washer, they will be my go to sock.
