Ultra Run Crew CoolMax Sock

You've been running just fine in traditional socks, or so you think, but when you run in the Injinji Men's Run Technical Crew Sock, you'll realize your toes have never been happier. This toe sock lets them splay out to their natural spread as your foot takes your weight, which in turn allows your entire foot to efficiently complete the stride. Wicking materials with a mesh instep panel pull sweat away from your foot and encourage airflow, to reduce the chafing that leads to blisters and let you finish your run in comfort.


  • Running socks for proper alignment
  • Technical material wicks away sweat
  • Toe splay allows for full-foot utilization
  • Individual toe design minimizes rubbing
  • Mesh knit on the instep for airflow
  • Item #INJ001D
68% nylon, 29% Coolmax, 3% Lycra

Best running socks

I've used it several times
Size Bought:
5' 10"

I love these socks. I've seen ultra runners use these and they swear by them so I fogured I would give them a try. Easy to say I am super impressed and will continue to wear / buy these socks again in the future. If you are on the fence, give them a try.

Best socks I own

I've put it through the wringer

I used to have issues with blisters between my toes. The injinji line was a game changer for me. These socks in particular, the Ultra Run Crew CoolMax Sock, are my absolute favorites for their comfort, cushion, and their durability. The awesome functionality of Injinji will quickly help you get past the odd look of toe socks and the extra 10 seconds it takes to put the sock on. No more inner toe blisters + comfortable toe splay for the win!
