Now that you have seen the reason why women wear heels, it is time, to begin with, the negatives. It is, as they say, one should know both sides of a story before you form conclusions. 

If you probably have poor toenail growth, it is mostly due to your high heels. Heels compress your toes and hence nails tend to grow inwards. Most of nail and fungal infections happen because of this. High heels also increase the risk of bunions.

The most common side effects of heels are hip and knee pains. Women tend to bend a little when wearing high heels which cause a strain in knee joints and hips. The more often high heels are worn, the more the strain on your hips, back, and calves. Most of the muscle pain you get is because of the heels you wear.
