How Grounding Footwear Works
For thousands of years, humans walked directly on the earth.
Grass, soil, sand, and stone allowed the body to remain electrically connected to the natural surface of the planet.
Modern life changed that.
Rubber and synthetic footwear insulate the body from the ground, interrupting the natural electrical exchange that historically occurred when walking barefoot outdoors.
Grounding footwear is designed to restore that connection.
ERTH CLASX approaches grounding through engineered performance materials rather than traditional barefoot design.

The Role of Conductive Materials
Grounding systems rely on conductive pathways that allow natural electrical charge to move between the body and the earth.
Two materials are particularly effective for this purpose:
Copper and Silver.
Both metals are widely used in electrical engineering due to their extremely high conductivity.

Copper Conductive Nodes
The TRI-GROUND™ outsole integrates copper conductive nodes positioned across a tri-point structure beneath the foot.
Copper (C110 grade) is one of the most efficient electrical conductors used in engineering.
Within the outsole, these nodes are designed to create contact points that allow the grounding system to interact with natural surfaces.
The tri-point layout distributes this contact evenly across the foot.

Silver Conductive Textile
Inside the shoe, ERTH CLASX uses a silver conductive textile footbed layer.
Silver fibers are woven into the textile structure to create a conductive surface that interfaces naturally with the foot.
Silver is the most conductive metal on earth, making it an ideal material for high-performance electrical transfer in compact systems.

The TRI-GROUND™ System
TRI-GROUND™ integrates four functional layers:
• Silver conductive textile
• Conductive comfort foam
• Copper grounding grid
• Copper node outsole
Together these elements create a continuous conductive pathway designed to reconnect the body with the earth while maintaining the comfort and performance of modern footwear.

Grounded Performance
ERTH CLASX was built to bridge two worlds:
Performance luxury footwear
and
natural grounding connection.
The result is a system engineered for modern movement while restoring a connection humans experienced naturally for thousands of years.
