This "invisible" sandal was created using the new material of nylon when it first became available. By winding nylon threads from the instep under the sole several times, the transparency of the nylon made the strap at the instep appear to float unsupported, fascinating everyone who sees the shoe. The wedge heel beautifully sculptured to resemble a letter "F" is also an idea attributed to Salvatore Ferragamo (1898-1960). The dramatic curve of the heel at first looks highly unstable, but it is actually backed by careful structural calculations that make the shoe comfortable to wear. This innovative use of materials, creation of new forms, and pursuit of functionality are testament to Ferragamo's dedication to shoemaking. For this sandal, he was awarded America's top fashion prize, the Neiman Marcus Award.
Salvaltore Ferragamo was born in Italy, began making shoes at the age of 9, opening his own shoe business at 11. Aged 15, he emigrated to the United States and found fame as a shoemaker with a strong clientele of Hollywood stars. Constantly searching for improvements and ideas, he studied anatomy at the University of Southern California, and employed the knowledge in his creations. In 1927, he returned to Italy and set up in Florence, making shoes for actresses and royalty throughout the world.
