# The sizes of sandals

The size of sandals is determined by the foot length l, which should be measured between the opposite points of its contour from the toes towards the heel.

For example: if the foot length l=21.1 (cm) the size of sandals would be 35, and with l=23.3 (cm) the size – 36.5.

Foot width parameter:

For determining the foot width the measurement of foot width is made. It’s is measured at the widest part of the foot.

Using the formula for calculating the foot width w=0.25b – 0.15c – a, where:

• b: foot circumference;
• c: foot length;
• a = 16 (cm) for women sandals size.

In the USA and Great Britain the foot width has letter marking, but they have obvious differences between each other.

For example: in English system the width C – for narrow foot, and in the USA marking system the width C – for a wide woman foot and for narrow man foot.
