Injinji Ultra Run Crew Coolmax® Socks - obsidian

Injinji Ultra Run Crew Coolmax® Socks - obsidian

Designed to provide comfort and support even after miles of wear, the Ultra Run Crew features padded terry throughout the foot and toe area to soften the impact of hard runs and workouts on the feet. The five-toe design prevents blisters, naturally spreads the toes and wicks away moisture. The Ultra Run Crew Sock, which is calf-high, features a ribbed cuff across the entire leg for a tighter, more ergonomic fit.

Features of the Injinji Ultra Run Crew Coolmax Socks

  • Blister prevention: skin-on-skin friction is completely eliminated on each toe to protect the foot from blisters and hotspots.
  • Moisture Management: each toe is wrapped in sweat-wicking material, keeping your foot drier and therefore more comfortable than in traditional socks.
  • Total Foot Utilization: when your toes are separated and properly aligned, this allows your whole foot to participate in any athletic activity.
  • Mesh Top: Provides maximum breathability and ventilation on the top of the foot.
  • Protective Padding: Additional padding on the footbed to increase foot comfort.
  • Padded Toes: Extra padding between the toes with medium weight terry cloth.


Material 64% polyamide, 33% polyester, 3% elastane
