The Pair Decides the Footprint
The biggest sizing mistake with footwear packaging is treating the labelled shoe size as the box size. Two pairs marked with the same size can need very different internal space because toe shape, sole width, heel height and upper volume change the geometry.
Custom Shoe Boxes should therefore be planned around the pair in its final presentation, not around a generic footwear chart. Place both shoes exactly as they will be packed, add stuffing, tissue, dust bags or spare laces and then measure the occupied footprint and height.
Orient Before Measuring
Decide how the pair will sit before dimensions are fixed. Trainers may nest differently from formal shoes. Heels can require more vertical clearance. Sandals can often sit in a shallower arrangement. Boots may force a completely different footprint.
Changing orientation can sometimes remove unused space without squeezing the product. Test more than one arrangement with the real pair before committing to a dieline.
Protect the Highest Point
The highest point is not always the heel. A structured tongue, raised ankle collar, decorative upper or stacked sole can sit closer to the lid.
Check the complete pair at rest. The lid should not press visibly into the footwear or rely on tissue compression to close. A close fit is useful, but contact pressure on suede, leather, embellishment or shaped uppers can create marks that a slightly better proportion would avoid.
