Shoes would be a difficult situation
An unidentified 6-year-old boy in Shenyang, China has a world record 31 digits: 15 fingers and 16 toes! He isn’t able to use all the fingers, as three are fused together in the middle of each hand. He will soon undergo surgery to reduce the number of extra digits to a more reasonable, functional amount…
The previous record was 25 fingers and toes, held by two children in India.
Most commonly, the extra digits appear on the little finger side of the hand – but this boy appears to have the much rarer condition of central polydactyly, in which the middle fingers and toes are duplicated.
You can see x-ray images of his hands and feet here.
