Why the Rhombus nail pattern? Unlike the standard Hexagon layout, the Rhombus (Diamond) pattern creates a different pressure distribution across your feet — delivering a varied, textured acupressure sensation. Combined with forged steel nails, this board offers a uniquely intense practice experience.

How to practice: Start with socks for a gentler feel and gradually progress to barefoot. The 10mm spacing provides a genuine challenge. Begin with just a few seconds and increase your time day by day. Just 1 minute on the Sadhu Board equals walking 2.6 miles barefoot — activating acupressure points, improving circulation, and sharpening mental focus.

Each board features a unique engraved design and natural wood grain — no two boards are identical. Two interlocking boards fit neatly into the textile case for safe storage and travel. Free worldwide shipping.
