Shaft circumference, length and calf circumference for boots
If you want to know the shaft circumference, length and calf circumference of boots, you can use the "Boot shaft circumference data sheet".
In this data sheet you can find the calf circumference, shaft circumference and shaft height(length) of each type of boot at size 37 (US-7) and the average increment (or decrement) per size.
Boot shaft circumference data sheet
Example of how to use this sheet:
You want to know the dimensions of the Electra-3000 and you have size 40 yourself. In the overview you search for 'Electra-3000' and there you will find the following information:

For size 37:
The calf circumference: 27 cm
The shaft height (length): 70.70 cm
The shaft size: 38 cm.
For size 40, you need to apply the average increase three times:
from size 37 to 38 = 1x, from 38 to 39 = 2x, from 39 to 40 = 3x
The calf circumference: 27 cm + 2.4 cm (3 x 0.80) = 29.4 cm
The shaft height(length): 70.70 cm + 4.50 cm (3 x 1.50) = 75.2 cm
The shaft size: 38 cm + 3 cm (3 x 1.00) = 41 cm.
The measurements for the Electra-3000 in size 40 therefore are:
calf circumference: 29.4 cm, shaft height(length): 75.2 cm and the shaft circumference is 41 cm.
