Slap

Slap (pronounced slap)

(1) A sharp blow or smack, especially with the open hand or with something flat; a sound made by or as if by such a blow or smack.

(2) By analogy, a sharply worded or sarcastic rebuke or comment.

(3) To put or place something promptly and sometimes haphazardly (often followed by on; if haphazard, often described as slapdash).

(4) As slap on the wrist, relatively mild criticism or censure, often used critically when more onerous punishments are available.

(5) A gap or opening, as in a fence, wall, cloud bank, or line of troops; a mountain pass; a wound or gash (now rare).

(6) As slap-sole, an additional sole affixed between the heel and sole of a high-heeled shoe.   

Origin uncertain: It’s been linked to the (1325–1375) Middle English slop from the Middle Dutch or Middle Low German (cognate with German Schlupf (hiding place)) though with little support.  The seventeenth century Middle English slappen is of uncertain origin and probably imitative, drawing from the Low German Slapp & Slappe (slap) from which Modern German gained Schlappe (defeat).  Most suggest the verb use (in the sense of “strike with an open hand”) began in the late fifteenth century, became an adverb in the 1670s, and picked up the meanings “suddenly” or “directly” in 1829.  The noun form dates from the mid fifteenth century, again apparently of imitative origin, similar to the various German forms slappe & Schlappe.  The figurative meaning "insult, reprimand" is attested from 1736; the now probably obsolete “slap-happy” (1936) originally meant "punch-drunk and “slap on the wrist” meaning "very mild punishment" dates from 1914.  The modern acronym SLAPP is unrelated.

Slap soles

Although they became high (and occasionally extreme) fashion items, slap soles began as a purely functional addition to men’s boots.  In the seventeenth century, men of a certain class, upon dismounting their horses, would slip a flat-soled mule over their riding boots to stop their heels sinking into the ground.  Presumably seeing a gap in the market, cobblers began to attach an additional sole, extending from tip to heel but not actually attached to the heel, a design which when walking, produced a clacking, slapping sound.  The apparently strange design existed so that riding boots would still fit securely in the stirrups and not interfere with the spurs.

Seventeenth century women's slap-soled shoes.

History doesn’t record whether women were attracted to the style or just the idea of being able to wear their newly fashionable high-heels without also sinking into the soil but the concept was soon extended to women’s shoes.  However, when applied to women’s shoes, although the slap-sole name stuck, there was no slapping sound when walking because the sole was this time anchored at the heel as well.  It’s essentially the same concept used on a tank or bulldozer, a self-laying track which renders a more stable surface on which to move.  So bizarre was the appearance of these shoes that they have long been a collectable and the delicate, intricate detailing on many does suggest many of them must have been created purely as pieces of high-fashion.  Doubtless there were some women of the horsey set who used the genuine slapping-soles as did the men but on the (admittedly hardly representative) basis of the surviving depictions, more seem to have worn them far from muddy stable yards.
