FAQ

What is Coolmax® and how does it differ fromcotton or nylon?

Coolmax® is a high-tech polyester fiber specifically engineered for superior moisture management. Unlike cotton, which absorbs and holds onto sweat (becoming heavy and cold), or standard nylon which can feel slick and less breathable, Coolmax® features a unique cross-section structure. It uses capillary action to pull moisture away from the skin to the fabric surface for rapid evaporation, keeping your feet significantly drier and lighter than traditional materials.

As one of the gold standards in performance textiles, Coolmax® is globally recognized and trusted by professional athletes and outdoor enthusiasts worldwide for its consistent ability to manage moisture and heat. When you see the Coolmax® label, you are looking at a product designed for serious performance, exceptional durability, and long-term foot health.

Which seasons and activities are best for Coolmax® socks?

While Coolmax® is the undisputed champion for summer heat and high-intensity training (like HIIT, running, and fitness), it is truly a multi-season fiber. Its ability to keep feet dry makes it excellent for any scenario where you might sweat, from spring hiking to intense indoor gym sessions. It is the go-to choice for athletes who prioritize thermal regulation and dryness year-round.

Do these Coolmax® socks help prevent blisters during high-intensity training?

Yes. Blisters are primarily caused by the combination of heat, moisture, and friction. Because Coolmax® eliminates moisture and reduces "hot spots" through its rapid-dry technology, it creates a much smoother environment for your skin. When paired with our anatomical fit, these socks act as a protective barrier that significantly lowers the risk of friction-induced blisters during your most demanding training sessions.

How should I wash and care for my Coolmax® socks?

To maintain the high-speed wicking technology and fiber integrity of your technical socks, follow these simple steps:

  • Machine Wash Cold: Use a gentle cycle (30°C) to protect the specialized Coolmax® fiber structure.
  • Wash Inside Out: Ensures a deep clean of the interior while protecting exterior patterns from friction.
  • No Fabric Softeners: Critical: Softeners clog the capillary channels, reducing the fabric’s ability to move moisture.
  • Air Dry or Low Tumble: These are rapid-dry socks; air drying is best to preserve the elastic Lycra for a long-lasting fit.
  • Avoid Bleach & Ironing: High heat and harsh chemicals break down synthetic polymers and ruin the technical performance.
