YouTube video by Lisa Sorrell explaining how she matches foot tracings and foot measurements to last sizes using bottom papers and last charts for three different last series
- shows her process for measurements taken seated and unweighted
- sets bottom papers 1/4 inch forward of the back of the heel in the foot tracing to allow for the projection effect of tracing with a pencil
- second last is a combination last
- C width in heel
- D width in instep
- E width in the ball
-
Munson last
- same length size as for the other two is too long
- last build-up for more toe room
- calculating widths not on the last chart by arithmetic grading
