There is a general categorisation for heels:
| Flat | | from flat mm to 25mm |
| Low | | from 25 mm to 60 mm |
| Medium | | from 60mm to 85mm |
| High | | from 85mm to 100mm |
| Very High | | over 100mm |
Also here, like for sizes, there is not a standard. There are 3-4 ways to measure them, usually localized.
American way:
The measured is taken placing the heel, with heel tip, on a flat surface and then measure from the surface to the top of the heel (in the back of shoe).
You can see it here:
Italian way:
The measure is taken on the heel axis (about the middle of the heel) without tips.
Italian way #2:
The measure is taken on the heel axis (about the middle of the heel) with tips.
Continental Industry way:
the masure is taken as in fugure and with tips.
An important thing to say is that the standard heel measurement is taken for all styles from a standard measure (usually 38EU/8USw).
So when you have a 5" declared heel this is the measurement for the size 38EU/8USw. For bigger sizes the heel will be highter, for lower sizes the heel will be lower.
This choice has a reson: a 5" real heel over a 34EU will give an highter arch than for a 38 and you feel to be, for that small size, to highter shoes; ie: heels height will decrease or increase according to size.
Usually the height varies with about 2-3mm for each size. For exemple: a 10cm declared heel will be 10cm for a size 38, 9cm for a size 35 and 12cm for a size 45.
Many scientis have tried to find a formula for the perfect heel.
This is a funny one:
The basic formula is : H = Q X [12 + (3 X S/8)]
H is the maximum heel height, in centimeters.
Q is the sociological factor and S is the shoe size;it must be a good enough base of support to keep you upright.
The Q factor of the formula
encompasses several variables and gets a bit complicated.
Here a extended version of Q:
Q = [P X L X (Y + 9)] / [(T + 1) X (A + 1) X (Y + 10) X (L + 20)}.
To further decode: P is the probability the shoes will land you a date or other flattering attention.
L is the price of the shoes, in British pounds.
T is the time elapsed since the shoe was the height of fashion (zero means it's red-hot).
A is the units of alcohol consumed while wearing the shoe.
Y is the years of experience wearing high heels.
Use this to decide if you have to buy a pair of high heels?
Surelly not, the main factor should be to be more sexy!
