The right gear can make or break any expedition. That's why Smartwool created the new PhD® Outdoor Mountaineer socks, their most technical mountaineering socks ever. Smartwool put some serious sock science to work in these all-mountain socks, including revolutionary Indestructawool™ technology for ultimate durability and the 4 Degree® elite fit system for a dialed fit. They placed high-density cushioning where you need it most, in the heel and toe, while using a flat knit on the leg to accommodate low-volume mountaineering boots. Mesh zones offer breathability, flex zones offer added comfort, and Merino helps keep feet warm, dry and comfortable.


  • Flex zone at ankle offers maximum flexibility
  • High-density cushion in heel and toe provide protection and comfort in high impact areas, while flat knit leg accommodates fit of low-volume mountaineering boots
  • 20-30 mmHg graduated compression rating helps post-activity recovery
  • Virtually Seamless™ toe
  • 14" overall height
  • Sock Height: Over the Calf
