Groundz Men’s Carbon Casual shoes are barefoot grounding slip-ons built for easy everyday wear. The upper is soft, matte-finish premium nubuck leather, giving the shoe a clean, understated look that works for walking, work, travel, and casual outfits in warm or cool weather. The foot-shaped design includes a wide toe box for natural toe room and a zero-drop, no-toe-spring platform that keeps the heel and forefoot level. A thin leather insole and cowhide midsole soften and mold to the foot after several days of wear. Minimal natural-latex padding at the heel adds comfort without heavy cushioning. Direct GroundSync™ technology uses a proprietary conductive carbonized-rubber interior outsole pad, supported by a solid copper rivet and silver conductive stitching. The gum-rubber outer ring provides grip and traction. Interior materials include a CR/metal-free buffalo-leather footbed and CR/metal-free sheepskin lining. Stack height is 8 mm, and each shoe weighs approximately 240 g in men’s US 9. Best for walking, everyday grounding on conductive natural surfaces, travel, and all-day casual wear.
