Hi Bullpod,
Have a look at this thread from a while back...

There's a fair few new-ish words there that you can look up, and a lot of it is described in Kevin Kirby's books:
Kirby KA: Foot and Lower Extremity Biomechanics: A Ten Year Collection of Precision Intricast Newsletters. Precision Intricast, Inc., Payson, Arizona, 1997.
Kirby KA: Foot and Lower Extremity Biomechanics II: Precision Intricast Newsletters, 1997-2002. Precision Intricast, Inc., Payson, AZ, 2002.
Or search around Podiatry Arena and you'll find a lot's of these terms explained...
Regards
Donna :)
