FAQ

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.
Can I wear Coolmax® socks in the winter? Will they feel cold?

Yes, especially for active winter sports. While Merino wool is better for static warmth, Coolmax® is ideal for winter activities where you still sweat (like indoor training or heavy-duty gym work). By keeping your feet dry, it prevents the "evaporative cooling" effect that happens when sweat turns cold against your skin, helping you maintain a consistent temperature.
