Step 4
Measure Heel-to-Instep
Place one end of the measuring tape at the back of your heel. Extend the tape diagonally along the side of your foot towards the highest point of your instep (the upper part of your foot).
Keep the tape following the natural contour of your foot without pulling it too tightly.
Record the measurement in centimetres (cm).
Important: Make sure you measure from the back of the heel to the highest point of the instep, following the same diagonal direction shown in the illustration.
