http://www.ncbi.nlm.nih.gov/pubmed/17367956.."Historians of the period have noted that Chinese men viewed foot-binding as conducive to better sexual intercourse because they believed that women with bound feet had vaginas that were more highly muscled and sensitive. We hypothesise that since foot-binding kept a girl's feet small and atrophic, this resulted in underutilisation of the foot areas of her somatosensory and motor cortices. This resulted in cross-activation between the redundant foot cortex and the adjacent genital areas in her brain. Hence women with bound feet devoted a disproportionately large area of the sensory and motor cortices of their brains to their genitalia and pelvic floor musculature, which made them more sensitive and pleasurable lovers. This caused Chinese men to prefer their sexual partners to have bound feet, which resulted in the enduring popularity of foot-binding in China over the last millennium"..
The factors to correlate foot length to height etc. are gender (and to a certain extent race) specific. Foot length seems to reach mature length much earlier than legs (femur, tibia). Given the impact on growth from estrogen it seems that women can have comparatively longer feet yet shorter legs and whence longer torsos. The reason that women have smaller feet is that they are shorter and there is a social aesthetic trend to wear too small shoes (in its most cruel form as the sexual fetish of Chinese foot bindings)! Woman's bicycle fit is, however, additionally complicated by the gender differences in muscle mass, flexibility etc.
