4 CONCLUSION
Fit is no doubt an important element in mating parts. With rigid components the
tolerances can be defined quite easily. With human tissue, the specification is more
complex due to irregular shapes and differing tissue properties. A poor fit between
feet and footwear can result in discomfort and injury in the long-term. Even though
an optimal fit may be difficult to achieve, the added cost will be a fraction of the
value associated with such a condition.
