In order to achieve proper shoe fit, it’s important to take into account volume. Volume = length x width x depth and when choosing a shoe you should try to match the volume of your shoe to the volume of your foot. I previously blogged about length using the Brannock Device which is the first component of volume. The following video shows you how to evaluate width and depth, the final components of volume.
Athletic shoe companies never talk about the upper or depth of a shoe. Instead they categorize shoes according to the lower (midsole) using terms like motion control, neutral or cushioning. Approaching shoe fit in this way only tells half the story and when you don’t take into account overall volume shoe fit and performance are compromised.
