There is legend to suggest a condition by the name of "THUMB TOES" discovered in Australia circa November 29, 1982 exists; whereby the "big toe" or the first, innermost, largest digit of the foot sticks up and somewhat resembles a "thumbs up". While much has been documented and reported about "toe thumbs" (big toes used in place of severed thumbs, usually as a result of abattoir/shopping related incidents), the THUMB TOE phenomenon still largely remains a mystery. Is it the next stage of evolution? Are humans to end up with thumbs as every digit on both our hands AND our feet? Only time will tell. The only thing we know for certain is stock in havaianas is sure to go up.
Slang for the medical condition Brachydactyly type D, aka Clubbed Thumb Syndrome. The condition results in short and broad thumb or pair of thumbs which will resemble the big toe.
