PhD® Run Ultra Light Wave Print Micro Socks
Run Harder. Run Farther
When you wear a run sock that's light on your feet, but tough on terrain, running just feels natural and better than ever. We've combined soft, natural Merino wool with powerful performance technologies to create our best-fitting, best-feeling running socks ever.
PhD® Run Socks
Technical, but comfortable. Durable, but soft. Innovative, but rooted in natural materials. Our PhD® Run socks keep getting better so you can too.
Get After It
We’ve gathered some Smartwool stories and run-inspired content to help get you motivated, on your feet, and on your favorite trail, road, or treadmill.
