where does the word achilles heel come from
Achilles' heel In Greek mythology, when Achilles was a baby, it was foretold that he would die young. To prevent his death, his mother Thetis took Achilles to the River Styx, which was supposed to offer powers of invulnerability, and dipped his body into the water; however, as Thetis held Achilles by the heel, his heel was not washed over by the water of the magical river. Achilles grew up to be a man of war who survived many great battles. One day, a poisonous arrow shot at him was lodged in his heel, killing him shortly afterwards.
Pointe shoe The birth of the modern pointe shoe is often attributed to the early 20th-century Russian ballerina Anna Pavlova, who was one of the most famous and influential dancers of her time. Pavlova had particularly high, arched insteps, which left her vulnerable to injury when dancing en pointe. She also had slender, tapered feet, which resulted in excessive pressure on her big toes. To compensate for this, she inserted toughened leather soles into her shoes for extra support and flattened and hardened the toe area to form a box.
