Salvatore Ferragamo was infatuated with the art of movement throughout his life. Surrounded by ballet dancers he dedicated his career as a designer to understand the mechanics of walking.  His discovery which he shared in his autobiography, Shoemaker of Dreams, was that 'the weight of our bodies when we are standing drops straight down on the arch of the foot". With that in mind, Salvatore Ferragamo created his shoes like timeless "Varina" ballet flats. A new book by Rizzoli is set to be released on the 21st of this month. Entitled Equilibrium, the book explores Ferragamo’s unique obsession with the relationship between the foot, the mind, and the evolution of walking.
