Injinji RUN Lightweight Mini-Crew

Visit the Injinji store

The Injinji RUN Lightweight Mini-Crew sock is crafted for runners who value comfort without compromising on performance. As the lightest sock in Injinji’s RUN series, it delivers a barely-there feel while still providing all the protection and support you need. The standout five-toe design wraps fabric around each toe to eliminate skin-on-skin friction, which is a common cause of blisters.

  • Prevents blisters by eliminating skin-on-skin friction between toes
  • Encourages natural toe splay for improved balance and grip
  • COOLMAX® fibres wick away moisture and keep feet cool
  • Ultra-thin cushioning for a lightweight, barely-there feel
  • Arch support and ergonomic fit ensure a secure hold
  • Mini-crew height offers ankle protection without overheating

Description

Constructed with COOLMAX® fibres and a breathable mesh top, this sock keeps your feet dry and ventilated during runs of any length or intensity. Its ergonomic, seamless construction offers a snug, supportive fit that won’t slip or bunch, while integrated arch support adds to the overall sense of security. The mini-crew height rises just above the ankle, giving you a balance of debris protection and breathable comfort.

Despite its ultra-thin cushioning, the sock doesn’t skimp on durability. The 200 needle-count knit ensures a high-density fabric that wears well while remaining lightweight. Whether you're training for a 5K or clocking up marathon miles, this sock is designed to help you go further in comfort and confidence.

Ideal for road running, gym sessions, or trail workouts in warm weather, the Injinji RUN Lightweight Mini-Crew is the perfect partner for runners seeking maximum freedom with minimal bulk.

How does it work

Injinji’s unique five-toe sleeve design allows each toe to move independently, which not only reduces friction but improves balance and stability by engaging the entire foot. This setup mirrors the foot’s natural movement and helps distribute impact more evenly during activity. The use of COOLMAX® fibres further enhances performance by pulling moisture away from the skin, keeping your feet dry and reducing the risk of blisters and irritation.

The mini-crew's ergonomic construction, including targeted arch support and a contoured fit, minimises bunching and slipping inside your shoes. The breathable mesh top helps regulate temperature, making these socks ideal for high-output sessions in warm conditions. All in all, the design supports your foot’s biomechanics while maintaining a low-profile, lightweight feel.

Injinji are the creators of the Performance Toe Sock. They are based in California and dedicated to the health and wellness of all things feet. Their patented, five-toe sock design improves any runners experience with their feet, by lessening the worry of discomfort, and creating more time for adventures and training.
