Standing on a properly made sadhu board is safe for healthy adults. The physics are simple: your body weight is distributed across 300 or more nail tips at once, so no single point exerts enough force to break skin. Skin is compressed, not punctured. Common-sense precautions apply: place both feet fully on the board, step on and off slowly with support, and avoid the practice if you have diabetes, neuropathy, open foot wounds, or bleeding disorders. Pregnant users and children should not practice. METADESK boards are built in Kostopil with hand-fitted nails to ensure even height and safe distribution.
Key facts

- Skin usually shows mild red dots that fade within an hour.
- Contraindications: diabetes, neuropathy, pregnancy, open wounds.
Frequently asked questions
Will the nails pierce my feet?
Not on a well-made board used correctly. Weight distribution across hundreds of points keeps individual pressure below skin-break threshold.
Should I disinfect the board?
Yes. Wipe nails with alcohol before and after each session, especially if sharing.
What if I have a foot injury?
Skip the practice until fully healed. Do not stand on a board with any open wound.
Are METADESK nails hand-fitted?
Yes. Roman Karas hand-fits each nail in the Kostopil workshop for even height.
