Groundz Women’s Copper Sandals are barefoot grounding T-strap sandals designed for natural movement, warm-weather walking, and all-day wear. The angled toe strap follows the natural line of the foot and flexes without pinching or constricting the toes, while the supportive ankle strap adds stability. The zero-drop, no-toe-spring platform keeps the heel and forefoot level. A 4 mm cowhide leather midsole starts slightly firm, then softens and molds to the foot with wear. Direct GroundSync™ technology combines a proprietary conductive carbonized-rubber outsole pad with a solid copper rivet and silver conductive stitching. A gum-rubber outer ring adds traction and flexibility on varied terrain. The straps, lining, and footbed use premium chrome-free sheepskin tanned with water-based vegetable dyes. A 3 mm natural-latex layer provides minimal cushioning while preserving ground feel. Stack height is 10 mm, and each sandal weighs approximately 225 g in women’s US 7.5. Best for: walking, light hikes, travel, grounding on conductive natural surfaces, and warm-weather everyday wear.
