Frequently Asked Questions

What are the best socks for ultra races?

The best ultra running socks will provide long term comfort and support for your feet. Injinji Ultra Run socks have cushion beneath the toes and underfoot to increase comfort. A mesh top and sweat-wicking fibers provide a cool, dry feel and by keeping the toes separate, blister-causing friction is eliminated.

What is the difference between Injinji's Ultra Run socks and Trail socks?

While Injinji's Ultra Run and Trail socks are both made with Midweight cushioning, the Ultra Run styles include extra terry padding throughout the toe sleeves and underfoot to help soften the impact encountered during ultras. The Ultra Run socks are the thickest running socks in the Injinji lineup. Both socks are great for blister prevention, moisture management, and total foot utilization, and the Mini-Crew and Crew styles keep out trail debris.

How do I choose the best Ultra Run sock height?

Choosing a sock height is all about personal preference. Injinji Ultra Run socks are available in No-Show, Mini-Crew, and Crew heights. The No-Show style sits below the ankle and includes a heel tab to prevent friction. For running on rugged trails, the Mini-Crew (ankle fit) or Crew (mid-calf fit) are both great options for sealing out dirt and debris.

Are Ultra Run socks comfortable?

Yes! Ultra Run socks, and all Injinji toesocks, wrap each toe in sweat-wicking fabric so your foot will be drier and more comfortable than traditional socks. When your toes are separated and properly aligned, your weight is distributed evenly which allows your entire foot to be engaged in any athletic activity.
