Static and dynamic sadhu boards: what actually moves
В мені · VMENI · Updated · 2 min read
Fixed-board nails stay in place; floating-board nails have designed movement under load. A floating construction can change individual contact heights as the foot loads them, while a fixed one retains its geometry. Choose by the mechanics you want, actual travel and serviceability, not by a promise of a stronger therapeutic effect.
When to consider a fixed construction
Choose this category when you want immobile nails and simpler mechanics without internal moving components. Check fastening, consistent projection and faults. A fixed design is not automatically a more authentic practice or a test of willpower.
What floating nails change
Within the designed range, an individual nail may move when loaded. This differs from a single fixed plane. Travel and resilience vary, so the name alone cannot predict every person’s sensation.
Movement, rotation and wobble
A rotating nail does not necessarily move vertically. Sideways play is not evidence of independent travel either. Ask for a demonstration and an explanation of normal movement. Sticking or falling out calls for inspection, not testing with your body weight.
The mechanism does not replace spacing
Spacing describes where the nails are placed; the mechanism describes movement. A floating board with a sparser grid is not automatically equivalent to a fixed board with a denser grid. Separate these two changes when comparing.
Care and replacement parts
Find out how the exact construction is cleaned, whether damp wiping is allowed, and which parts can be replaced. Do not dismantle it without suitable instructions. Paying extra makes sense when you want the function and understand its upkeep, rather than merely liking a label.
