“The foot is built in the form of a half-dome or half-arch. This is to afford a broad, strong support surface for the support of the weight of the body. The bones of the toes and the heel form the piers, while the little bones wedged in between the metatarsal bones and the heel make up the keystone of the arch. This arch gives a certain amount of spring and elasticity to the feet, and hence it is of the upmost importance in preventing jars and jolts.” — Blaisedell, 1904
