Bastinado

What is bastinado?

Bastinado (also called foot whipping, or falanga / falaka in the medical literature) is striking the bare soles of the feet with a stick, cane, or whip. Within BDSM it is a form of impact play that hurts sharply without leaving much visible behind. Outside BDSM it is a well-known torture method, and that is where almost all of the knowledge about it comes from.

Why the sole reacts so sharply

The sole is built to spread pressure, not to catch blows. There is a dense layer of nerve endings just under the skin, and little tissue sits between those nerves and the bone.

The encyclopedia puts the difference with other impact work briefly: unlike most forms of flogging, it is meant to cause pain rather than to actually inflict injury. That is why it has been used as a torture method, and why it appeals in BDSM: a lot of sensation, few traces.

What the literature shows about repetition

One thing belongs here honestly. What repeated, hard striking of the soles does over the long term has mostly been studied outside the bedroom, and the result is not mild.

Longstreth and colleagues described in The American Journal of Medicine people in whom pigmentation spots on the soles were still present years later, and in some, pressure pain stayed.

That is a different order of violence than a consensual scene, and it would be unfair to equate the two. But it does show where the upper limit lies: the sole recovers poorly from repeated hard blows, and the damage sits in the tissue and the nerves rather than at the surface. Which is why building up and taking breaks make the difference here.

Why people do it anyway

The appeal is in the intensity at low force. A tap that barely registers on a buttock is an event on a sole. That makes bastinado suited to people who want a lot of sensation without much force, and to scenes where someone is tied down and cannot get away.

For the one giving, it appeals because it is slow. There is no room for big gestures; it comes down to rhythm, placement, and pauses.

The visibility it lacks makes it easier to go too far. There is no reddening skin to warn you.

How people build it up

The usual route starts soft and short. First by hand, then with something light, in series of a few taps with pauses in between where the one receiving can move the foot.

What separates the careful execution from the sloppy one is where the strikes land. The fleshy ball of the foot and the middle of the sole take it best; the heel and the edge of the arch are where the tendon sheet and the bone lie just under the skin.

Afterward, walking is the problem, not the pain itself. Anyone who still has to drive for an hour or walk home after this will feel it, and that is the reason to do it at the end of an evening rather than in the middle.

Misconceptions about bastinado

“Nothing is left behind, so it can’t do any harm.” The absence of bruises says nothing here. The studied damage from falanga sits in the tissue and the nerves, not in the skin.

“It’s the same as spanking, just in another spot.” With spanking a thick fat layer cushions the blow. With bastinado there is none.

“If someone can take it, things are fine.” Taking it is no gauge with this form, because the pain builds slowly and the effect comes afterward.

What I make of it

Bastinado is one of the few things where I keep count instead of working on feel.

It surprises people almost every time. Someone who handles a firm spanking without trouble will say by the fourth tap on a sole that it is enough. That difference in scale is real, and it is not a matter of getting used to it.

On a BDSM date I always agree in advance on how many taps there will be, and then a pause. In this spot, counting works better than asking how it feels, because the answer only comes half a minute later.

What you can do yourself

• Agree in numbers, not in intensity. Series of five with pauses in between show you what you are doing.
• Stay off the heel and the edge of the arch. That is where bone and tendon plate lie just under the skin.
• Do it at the end of the evening, because walking is the first thing that disappoints afterward.
• Don’t repeat it in a short span. The damage described in the literature comes from repetition, not from one time.
• Stop at a dull, burning feeling that stays instead of fading between the series.

Further reading on bastinado

On this site, the article on the cane covers the tool most often used for this, and the difference between sharp and dull pain covers why the same force does something different in different spots.

Off this site, the article by Longstreth and colleagues is the most honest thing there is about what repeated striking of the soles does over time.
