ELI5: Explain Like I'm 5

Toe cleavage

Toe cleavage is like the crack you see between your toes when you wear shoes that show a little bit of your toes. Imagine if you wear a closed shoe like a cowboy boot, only the top part of your toes are visible, but when you wear a shoe with a pointed toe, your toes might peek out a little bit, leaving a tiny gap that looks like a line between them. That little gap is called toe cleavage. It's similar to the crack between your buttocks when you bend over, but it's much much much much much much much much much much smaller and on your feet.
