Suicide heel

At one point in time it was common for men's shoes to have leather heels. In order to reduce their wear they would have metal cleats set into them. Stepping on a smooth or wet surface was "suicide" since you'd very possibly fall down.

"I love these leather soles but I about broke my tailbone when I fell from these suicide heels"
"One more fall and I swear I'm getting these suicide heels replaced with rubber."
