Negative foot impression for the manufacture of a total contact foot orthosis
applied, both beneficial effects. When coupled with an increase in the
contact area between foot and footwear (using an orthosis), cushioning
materials can be very effective in reducing foot pressures. Recent work
has shown how combining knowledge of both foot shape and foot pres-
sure distribution (contact pattern) to inform orthotic design can provide
improved reductions in plantar pressure compared with orthoses designed
using only foot shape (
