HEEL WEAR AND TEAR
a. Daily Activities and the Heel. Smaller than a golf ball, the heel (calcaneus
bone) is the largest bone in the foot and withstands much wear and tear from our daily
activities. Soft protective tissue about 3/8ths of an inch thick lies between the bone and
the sale of the foot. This tissue wears down easily. Running places a great deal of
strain on the heel. A person running places three times his weight on his heel. This
pounding of the heel on a hard surface such as the pavement or firm ground can be
compared to the pounding of a sledgehammer against an unyielding surface.
