Cicero, Leonardo da Vinci and Shakespeare all thought that eyes were the windows to the soul, but with due respect to the big dogs, I beg to differ. It is shoes which tell you everything. Hype trainers worn with a bland suit; teetering heels worn in defiance of practicality; scuffed ballet pumps; haute hiking boots or polished brogues – shoes hold the clues to what you do all day and how you get there, to whether you really want to be at the party and who you are going home with.
