Jennifer Garner is one of many A-list stars who have their own unique physical quirk. Back in 2013, Garner was spotted by paparazzi with her hair up in a ponytail running errands in Brentwood, California (via The Daily Mail). Upon closer examination, viewers noticed that Garner has an unusual-looking pinky toe that is slightly overlapping with her ring toe. As it turns out, this is caused by a minor condition known as brachymetatarsia.

According to Radiopaedia, brachymetatarsia is a rare and genetic condition that mostly affects people who are born female. The condition usually occurs when the toe's bone fails to properly develop or its growth plate closes prematurely. Brachymetatarsia can be diagnosed with a simple x-ray, and, although the health matter can be resolved through various toe lengthening treatments, in some cases individuals with brachymetatarsia don't experience any discomfort or pain (via Foot Health Facts).
