Dear BIOMCH-L members;



I am currently looking to acquire information pertaining to
the effectiveness of force absorption in the mid sole of brand name
running shoes. This project is focused on the development of an
effective evaluation system to grade running shoe performance. The main
focus of my contribution to the study is to examine the performance of
different mid sole designs and the force absorbing characteristics in
the heel to ground impact. The data is currently being collected using
an A.M.T.I. force plate at Lakehead University. The sled is weighted
and is equipped with a prosthetic foot (size 9.5) at an incline of 10.
This data will then be compared with the results of barefoot trials in
order to assess the effectiveness of different shoe designs. The
collection of data is set to augment a larger study which is examining
the equivalent impact forces on human subjects during walking and
jogging over a floor mounted force plate. A pilot study is in the works
to expand the sled data to examine the durability of various mid soles
during prolonged use (i.e. marathon use). We are currently looking for
information pertaining to: K constant of proportionality (sole material
properties), time to peak force, and compressibility of various
materials used in mid-sole design.

Thank you in advance for your assistance.
