Foot index: Is it a tool for sex determination?
Moudgil R, Kaur R, Menezes RG, Kanchan T, Garg RK.
J Forensic Leg Med. 2008 May;15(4):223-6.

Identification of an individual is of paramount importance in forensic investigations. The dimensions of the foot can be used for the determination of sex and stature of an individual in forensic investigations. No systematic studies are available on the determination of sex from foot measurements of North Indians. Therefore, foot index is derived to determine the sex of an individual in a single community of North India. The foot index for both genders is derived by dividing the foot breadth by foot length and multiplying it by hundred. In the present investigation, the foot index is found to be slightly higher in females in the right foot and males in the left foot. The study suggests that although foot length and foot breadth show significant sex differences, sex determination cannot be made conclusively from the foot index.

Sex estimation in a modern American osteological sample using a discriminant function analysis from the calcaneus.

Forensic Sci Int. 2012 Apr 16.

Reliable methods for sex estimation during the development of a biological profile are important to the forensic community in instances when the common skeletal elements used to assess sex are absent or damaged. Sex estimation from the calcaneus has potentially significant importance for the forensic community. Specifically, measurements of the calcaneus provide an additional reliable method for sex estimation via discriminant function analysis based on a North American forensic population. Research on a modern American sample was chosen in order to develop up-to-date population specific discriminant functions for sex estimation. The current study addresses this matter, building upon previous research and introduces a new measurement, posterior circumference that promises to advance the accuracy of use of this single, highly resistant bone in future instances of sex determination from partial skeletal remains. Data were collected from The William Bass Skeletal Collection, housed at The University of Tennessee. Sample size includes 320 adult individuals born between the years 1900 and 1985. The sample was comprised of 136 females and 184 males. Skeletons used for measurements were confined to those with fused diaphyses showing no signs of pathology or damage that may have altered measurements, and that also had accompanying records that included information on ancestry, age, and sex. Measurements collected and analyzed include maximum length, load-arm length, load-arm width, and posterior circumference. The sample was used to compute a discriminant function, based on all four variables, and was performed in SAS 9.1.3. The discriminant function obtained an overall cross-validated classification rate of 86.69%. Females were classified correctly in 88.64% of the cases and males were correctly classified in 84.75% of the cases. Due to the increasing heterogeneity of current populations further discussion on this topic will include the importance that the re-evaluation of past studies has on modern forensic populations. Due to secular and micro evolutionary changes among populations, the near future must include additional methods being updated, and new methods being examined, both which should cover a wide population spectrum.

We found that sex could be identified from patterns of morpological variation found within the interplay of several dimensions of individual tarsal elements. Generally, utilising the 1st-4th principal components from a logarithmically transformed set of interlandmark distances computed on the covariance matrix, the sex difference on usually the third, but sometimes the fourth. This was a constant, no matter where we looked, from Roman Britain, right through to Pre-contact Amerindians, even in Eskimos from Kagamill Island. The calcaneus and cuboid were the most reliable, thus saying something abouth the lateral column. The foot is remarkable in what it says. Rob

I can correctly determine the sex of a patient 100% of the time by examining the area between the big toes.

I wonder how my friend T**** measures up since she's been a she from when she was a he?
I somehow doubt that I'll ever ask her.
