What is the word for a trait that is actually a handicap but implies good health and mating prospects?

The classic example would be peacock feathers. Female peacocks mate with males with the fancier displays – even though they are more attractive to predators and cannot fly as well as a male with short feathers. Another example would be deer antlers. The large rack gets caught in brush and low branches but supposedly a deer that can survive with the large rack must be stronger than one without a rack.
There is an expression for this: a ”(something) handicap”.

Can you think of examples that apply to humans?
First one that comes to my mind is high heels. They are uncomfortable, difficult to run in, but they sure look sporty and if a woman can walk in those, she must have a certain desirable physical attributes.
What is this handicapping process called?
