Fourth Element Thermocline Fin Socks: The Ultimate Problem-Solver for Your Feet!

The Fourth Element Thermocline Fin Socks are the ultimate problem-solver for your feet. Whether you need to prevent painful blisters from your full foot fins, add a layer of warmth to your dive boots, or create a barrier against neoprene allergies, these comfortable and eco-conscious socks are the perfect solution.

The Ultimate Multi-Tool for Your Feet:

These versatile socks are designed to improve your comfort in several ways.

  • Prevent Blisters: Worn with full foot fins, they create a soft, protective barrier with comfortable flatlock stitching that eliminates the rubbing that causes sores and blisters.
  • Add Warmth: Wear them as a liner inside your regular neoprene dive boots to add the equivalent warmth of 2mm of neoprene—a perfect thermal boost for cooler water.
  • Beat Neoprene Allergies: As a completely neoprene-free garment, they create a hypoallergenic barrier between your skin and a traditional neoprene boot.
  • Perfect the Fit: They can help a pair of fins that are slightly too large fit more snugly, which is a great feature for kids with growing feet.

Good for the Ocean, Great for You:

As part of Fourth Element's OceanPositive collection, these socks are made from a unique technical fabric that utilizes ECONYL® recycled nylon, regenerated from lost or abandoned "ghost" fishing nets. The inner fleece wicks moisture, while a breathable membrane helps with thermal regulation on the surface. The fabric is neutrally buoyant, machine washable, and dries incredibly fast, making it the perfect travel companion.

Solve all your in-water foot problems with one incredible sock! Order your pair of Fourth Element Thermocline Fin Socks today!

Features
  • Neoprene-Free: The perfect solution for individuals with neoprene allergies, acting as a protective barrier inside boots.
