Sex and the City stars stay upright because h = Q.(12+3s/8) say scientists
As Sex and the City's Carrie finally wanders off the UK's television screens, physicists at the Institute of Physics (London, UK) have devised a formula that high-heel fans can use to work out just how high they can go. Based on your shoe size, the formula tells you the maximum height of heel you can wear without toppling over or suffering agonies.
h = Q(12+3s /8)
h is the maximum height of the heel (in cm)
Q is a sociological factor and has a value between 0 and 1 (see below to work this out)
S is the shoe size (UK ladies sizes). This factor makes sure that the base of support is just good enough for an experienced and sober, high-heel wearer not to fall over.
