1. Put a foot (in thin socks) on the sheet of paper and carry a bodyweight on a foot. You will ask somebody to describe the contour of foot a sharp-cut pencil (pic.1).

2. Measure the got contour of foot between two remotest points (pic.2). you will round off a result to the whole number 0 or 5 (for example: 24,2 cm = 24 size; 31.6 cm = 31,5 size; 19,4 cm = 19,5 size)

Conduct measuring just like this, as written and drawn on the proper pictures. A pencil must not call under a heel, as it is rotined on a picture, I.e. you must describe and measure the projection of track, abandoned a foot. Measurings conducted by you are enough in an order to process an order.
