Update on women's footwear.

Shoes have been implicated as being responsible for the majority of foot deformities and problems that physicians encounter in women. In our original study of 356 women, the majority of women studied wore shoes that were too small for their feet, had foot pain and deformity, and had increased in shoe size since the age of 20. The women without foot pain or deformities also wore shoes that were smaller than their feet but to a lesser degree. In the present study, data on 255 of the original 356 women are evaluated. Tracings were made of the standing foot and the shoe. Measurements were made of forefoot and the heel width. An index of forefoot width to heel width was developed. The indices do not vary much among women. Based on linear measurements, as forefoot width increases, so does heel width. As foot length increases, forefoot width increases to a greater extent than heel width.
