Big Foot – for Real

October 14, 2018

That pair of feet looks HUGE, doesn’t it? It’s not just because the person taking the picture snuck up close. Jeison Hernandez has the world’s biggest feet. At almost 16 inches long, they’re longer than a real 12-inch “foot”! Of course, taller people have longer feet, and Jeison himself stands over 7 feet tall. Even so, his size 26 feet still shock and amaze everyone who sees them. In the whole history of the world, the biggest feet ever were bigger than that. Back in the 1930s, the world’s tallest man, Robert Wadlow, had feet 18 1/2 inches long, and wore a size 37AA shoe. All we can say is, don’t try to play soccer against these guys.

Wee ones: Stand next to a grown-up so your feet are side by side. Whose feet are longer?

Little kids: Hold your right foot against your left forearm (the part from your elbow to your wrist). Which one is longer?  Bonus: How much taller would you need to grow to stand 7 feet tall like Jeison? Find out your height rounded to the closest foot!

Big kids: If Jason wears a size 26 shoe, how many sizes bigger were Robert’s size 37 feet?  Bonus:For grown-ups, a jump of 3 shoe sizes equals 1 inch in shoe length. If Jason is size 26 and your feet were 6 inches shorter, what shoe size would you wear?

 

 

 

 

 

 

 

 

 

Answers:
Wee ones: The grown-up’s feet are probably longer!

Little kids: Cool fact: on most people, the foot and forearm are close to or exactly the same length!  Bonus: Different for everyone…find out your height in feet, then subtract from 7.

Big kids: 11 sizes bigger.  Bonus: Size 8, since your feet would be 18 shoe sizes shorter.
