How do you write a URL in Latex?

The subscripts and everything else make the font look very strange when it compiles.

You can use \url

\usepackage{hyperref}
\url{http://stackoverflow.com/}

---

You just need to escape characters that have special meaning: # $ % & ~ _ ^ \ { }

So

http://stack_overflow.com/~foo%20bar#link

would be

http://stack\_overflow.com/\~foo\%20bar\#link

Here is all the information you need in order to format clickable hyperlinks in LaTeX:

Essentially, you use the hyperref package and use the \url or \href tag depending on what you're trying to achieve.

A minimalist implementation of the \url macro that uses only Tex primitives:

\def\url#1{\expandafter\string\csname #1\endcsname}

This url absolutely won't break over lines, though; the hypperef package is better for that.
