Who is this board for? This board is ideal for practitioners who already practice comfortably on 8mm or 10mm boards. The 12mm spacing delivers deeper, more concentrated pressure on each nail — a stronger, more challenging experience that builds focus, resilience, and mindfulness. Note: individual experience varies based on body condition, balance, and pain tolerance.

Custom-made nails. These are not standard construction nails — they are specially designed and produced exclusively for TENGRY Sadhu Boards, optimized for standing-on-nails practice.

How to practice: Begin with short sessions and gradually increase time as your body adapts. Socks can be worn to soften intensity. Progress mindfully at your own pace.

Two interlocking boards fit neatly into the velvet case for travel, retreats, or daily home practice. Free worldwide shipping.
