But it is not possible to estimate the distance on inside the shoe from outside and is often significantly lower than you would think (winding, seams, footbed).
A suitable measurement instrument such as the Brannock Device is far easier to use. Only 35% wear the right dress, and only 11% have space for “growth.” Think again if you believe data about shoe size is always correct.
Then inspect the room on the heel with the other side. To see the space there is to develop, the thumb is pressing the toe of the shoe.
Brannock has created a measuring tool to readily get the human foot’s length, breadth, and arc length. However, did you know that the foot length should be added to at least 0.5 –0.7 inches (12–17 mm)?
