[pct-l] Foot Expansion

[Diane Soini of Santa Barbara Hikes]

Anyone who is a doubter about the foot under load, foot deformation  
due to shoes and other foot/boot related issues may find this old  
book interesting. There are some great x-rays of feet inside boots  
and some interesting military boots from all over the world lined up  
so you can see differences in shape.

The soldier's foot and the military shoe: a handbook for officers and  
noncommissioned officers of the line, Volume 1912 by Edward Munson  
(ever heard of the Munson last?)
