3.9 cm wide stainless steel ankle shackles — Allen key

Two solid steel ankle cuffs connected by a thick link chain — 1.3 kg of metal pinning the ankles to the ground. Each cuff is 3.9 cm wide: impossible to forget, impossible to remove without the provided Allen key. The sub feels every gram with every step.

3.9 cm wide, the weight of metal on the skin

The width of the cuffs distributes pressure over a large area of the ankle — less risk of concentrated marks than with thin handcuffs. The polished steel is smooth on the inside, without burrs or sharp edges. It remains comfortable even for prolonged wear during a session, provided that the 9.4 cm diameter matches your morphology. Measure your ankle circumference before ordering.

Allen key lock: zero escape

Each cuff locks with a screw and the included Allen key. Once closed, it doesn't move — the sub can pull, twist, struggle, the metal won't budge. The Allen key is discreet and easy to keep on hand. The locking system is integrated into the cuff, no dangling or snagging padlocks.

The chain dictates the range of motion

The links between the two cuffs allow just enough play for small steps — not enough to run or spread the legs freely. The chain is made of solid steel, the same caliber as the cuffs. Combine these restraints with wrist cuffs for complete immobilization, or with a spreader bar to force the legs open.
