If you've ever looked at a pencil and wondered what it would be like to walk around on one, then you're not alone. The stiletto heel is often referred to as the pencil heel, and it's easy to see why. These ultra-thin heels are typically less than an inch wide, and they can range in height from a few inches to six inches or more. While stilettos are usually associated with glamour and sex appeal, they can also be quite dangerous. In fact, these slender heels are one of the most common causes of foot injuries. So next time you're admiring a pair of sky-high stilettos, remember that beauty comes at a price.
