Question: How does the raised heel help?

Candidate passages:
A heel is the projection at the back of a shoe which rests below the heel bone.
The shoe heel is used to improve the balance of the shoe, increase the height of the wearer, alter posture or other decorative purposes.
Sometimes raised, the high heel is common to a form of shoe often worn by women, but sometimes by men too.
See also stiletto heel. 
Mediæval Europeans wore wooden-soled patten shoes, which were ancestors to contemporary high heels.
Elizabeth Semmelhack, curator at Toronto's Bata Shoe Museum, traces the high heel to Persian horse riders in the Near East who used high heels for functionality, because they helped hold the rider's foot in stirrups.
She states that this footwear is depicted on a 9th-century ceramic bowl from Persia.
It is sometimes suggested that raised heels were a response to the problem of the rider's foot slipping forward in stirrups while riding.
The "rider's heel", approximately high, appeared in Europe around 1600.
The leading edge was canted forward to help grip the stirrup, and the trailing edge was canted forward to prevent the elongated heel from catching on underbrush or rock while backing up, such as in on-foot combat.
These features are evident today in riding boots, notably cowboy boots. 
One variable in gait is ' – how the foot contacts the ground, specifically which part of the foot first contacts the ground.
' – toe-heel: ball of foot lands first  ' – heel and ball land simultaneously  ' – heel-toe: heel of foot lands, then plantar flexes to ball In sprinting, gait typically features a forefoot strike, but the heel does not contact the ground.
Some researchers classify foot strike by the initial center of pressure; this is mostly applicable to shod running (running while wearing shoes).
In this classification:  a rearfoot strike (heel strike) has the initial center of pressure in the rear third of the shoe (0–33% of shoe length);  a midfoot strike is in the middle third (34–67% of shoe length);  a forefoot strike is in the front third (68–100% of shoe length).
Foot strike varies to some degree between strides, and between individuals.
It varies significantly and notably between walking and running, and between wearing shoes (shod) and not wearing shoes (barefoot).
Typically, barefoot walking features heel or midfoot strike, while barefoot running features midfoot or forefoot strike.
Barefoot running rarely features heel strike because the impact can be painful, the human heel pad not absorbing much of the force of impact.
By contrast, 75% of runners wearing modern running shoes heel strike; running shoes being characterized by a padded sole, stiff soles and arch support, and sloping down from a more padded heel to a less padded forefoot.
The cause of this change in gait in shoe running is unknown, but Liebermann noted that there is correlation between the foot-landing style and exposure to shoes.
In some individuals, the gait pattern is largely unchanged – the leg position and foot position are identical in barefoot and shoe running – but the wedge shape of the padding moving the point of impact back from the forefoot to the midfoot.
In other cases, it is conjectured that the padding of the heel softens the impact and resulting in runner modifying their gait to contact further back in the foot.
A 2012 study involving Harvard University runners found that those who "habitually rearfoot strike had approximately twice the rate of repetitive stress injuries than individuals who habitually forefoot strike".
This was the first study that investigated the link between foot strike and injury rates.
However, earlier studies have shown that smaller collision forces were generated when running forefoot strike compared to rear-foot strike.
This may protect the ankle joints and lower limbs from some of the impact-related injuries experienced by rear-foot strikers.  
South started wrestling in 1985 in the NWA's Jim Crockett Promotions (JCP).
He was used as enhancement talent but he always got in some offense and was very good at getting heel heat with the fans.
He was also Ric Flair's favorite jobber to wrestle as Flair considered him a great worker.
South also worked with Gary Royal in the masked jobber tag teams the Cruel Connection, Mexican Twin Devils and the Gladiators.
As the Gladiators, South and Royal jobbed for Bill and Randy Mulkey giving the perennial jobber tag team their only televised win on World Championship Wrestling.
South wrestled in Georgia Championship Wrestling and captured their NWA Georgia Junior Heavyweight Championship in 1986 in between stops for JCP.
In a brief time, South also wrestled as a preliminary wrestler in World Wrestling Federation in the late 1980s.
South was the top heel in the Pro Wrestling Federation that ran from 1992 until 1999 in the Carolinas.
He mainly feuded with his arch-rival, The Italian Stallion, who promoted the company with some help from South.
In the 1990s, South worked as enhancement talent for World Championship Wrestling.
South is a born-again Christian and says one of his biggest thrills was passing a Christian tract to Hulk Hogan in WCW who told him he needed it.
In 1999 three full-color cartoon tracts were produced for South entitled "The Greatest Match Ever", "Who is Your Tag-Team Partner?
", and "Who Are You Wrestling Against?
", illustrated by comics artist Steven Butler, packaged by The Nate Butler Studio and published by PowerMark Productions.
When the PWF closed in 1999, South opened his own promotion called the Exodus Wrestling Alliance.
He still runs shows as of 2005 in the Mid-Atlantic area and participates in Christianity/wrestling shows with Nikita Koloff and Ted DiBiase.
One of his gimmicks is the fact that he gets heel heat from the fans by sticking his tongue out at them and taunting them about how he is manhandling their hero in the ring.
He is proud of the fact that he does not have to get crude, use profanity, or become vulgar to get heel heat.
An important part of South's modern day matches are moves and performances intended to pay tribute to the great wrestling stars of the 1960s, 1970s, and 1980s, including Wahoo McDaniel, Blackjack Mulligan, Brute Bernard, Two Ton Harris, Paul Jones, Ricky Steamboat, Tully Blanchard, the Anderson Brothers, and others.
South's most significant recent match was against Brad Armstrong in Spartanburg, SC at the Wrestling Night of Legends II.
It is considered, by those who follow the current independent scene and the recent trend of legends reunions, to be a textbook look at everything that was right about "old school" wrestling.
South trains up and comers at the Rings wrestling training facility in Charlotte, North Carolina on Tuesdays.
His son, George South Jr., is also now a wrestler. 
Share Our Strength magnifies funds through corporate sponsorships that make it where every dollar donated is increased through matching donations and more effective outreach.
In this way, donations made to Share Our Strength can purchase significantly more help for children at risk of hunger than a similar donation made directly to one's local food bank.
Funds are also magnified by how Share Our Strength allocates monies.
While the vast majority of funds are granted out to the same community in which they are raised, the remaining funds are instead allocated to locations where they can make the most difference for the least amount.
This method of reallocation ensures that every dollar spent does as much as possible to help children in need.
