Physical properties

Hardness: Shore A 30-40 (very soft, flexible); Color: Marbled blue, green, and white; Luster: Matte to waxy; Texture: Closed-cell resin foam with circular drainage perforations.

Formation & geological history

Formed via injection molding of foamed ethylene-vinyl acetate (EVA) resin. Modern era (21st century); manufactured in factory environments using heat and high pressure.

Uses & applications

Primary use is in the footwear industry for ergonomic comfort, water resistance, and leisure wear.

Geological facts

This material is proprietary and known for being lightweight and odor-resistant. While it mimics the swirls of metamorphosed minerals like marble, it is entirely synthetic and lightweight enough to float on water.

Field identification & locations

Identify by its flexible, rubbery texture and distinct ventilation holes. Commonly found in residential areas, suburban lawns, and near water bodies. Often left outdoors; not found in natural geological strata.
