I like to run outside and therefore need shoes to run. However, there's a massive market for running shoes and I get lost in all of the options. What are some guidelines in selecting a good shoe for running?
(Note: I'm not looking for "which is best" but rather, what technology or features should I look for)
Disclaimer: I've worked for a company that makes pressure plates, that allow you to analyze running patterns (with or without shoes). I've done research at a specialized running shoe shop and my father is an orthopedic shoe manufacturer. So in short, my opinions are fairly biased, but by no means scientifically proven.
While md5sum names some great rules of thumb, they apply to every shoe and don't help you determine what type of shoe you're looking for.
First a short note: Adidas did a study way back in 1987 and found that most injuries come from:
Injuries caused by training:
Injuries caused by shoes:
As you can see, picking the right kind of shoes is pretty darn important! So how do we pick one?
When you dissect a shoe, it's made up out of two main components:
The first component is composed the same for nearly every pair of running shoe. While the last around which it is made, may or may not fit your foot (see md5sum's answer for some excellent advise there), you won't find much variety within a certain brand. However, you should note that this is mostly true for the running shoes. Don't even consider running on those cheaper aerobic or tennis models, because you'll fall in the trap Adidas found earlier.
The other component, which is the sole of the shoe. Now when I say sole, I'm actually referring to everything that is below your foot when you're inside the shoe. Trying to discuss all the bits and pieces that compose it depends strongly on the brand and their design-department.
When limiting choices towards endurance running and excluding fancier shoes that are meant for trail running or sprinting on a track. You're left with a shoe sole that serves several functions:
Shock absorption is mainly determined by your body weight, rather than the type of shoe. When you're lighter, you can get away with having a 'softer' (as in lower shore values) soles than when you're heavier. When I say shock absorption, don't immediately think: Nike Air! because most absorption comes from flexing your joints, rather than compressing your sole.
There are several 'special' features for motion control, though you can safely assume that unless you have some severe disorder, you probably don't need any of the extreme models. With extreme, I mean shoes with extreme angles at the heel or other gimmicks:
If you're 'normal' you fall in one of three groups: those who pronate too much, those who run neutral, those who don't pronate enough (or supinate). Don't mistake this for the other three types people like to call out: flat, normal arched and high arched feet. Hate to break it to them, but since the shoes all have the same shape on the inside, they surely aren't adapted to your arch! No I'm talking about biomechanics here:
These pictures depict the maximal motion in this subjects ankle, that your running shoe is trying to limit. Funny enough, I almost never encounter shoes that help against eversion (supination), so choice boils down to: how much pronation do you have, ranging from excessive to normal?
This boils down to three main types of shoes:
So how do I know which one I need?
Well one easy way of determining this is looking back at your history:
If you're overweight and you have a history of pronation-related injuries then yes, probably you need the heaviest kind of support you can get. In most other cases, the neutral shoe is of such decent quality that you don't need anything else.
So isn't there any choice at all?
Well, yes all the brands will tell you they have superior technologies built into their shoes and they're all right. But sadly for them, that technology also has to fit your foot. When you take 5 different brands and you start to test them on a treadmill, you probably end up having to chose between two brands, because the rest 'didn't feel right' and you end up picking the one with the fancy colors.
What do I do if I want to start with running and don't know what's good for me?
Typically, it depends on many things, but any good running shop should be able to advise you based on your conditions. What's your posture, age, physique, level of activity, general health, your goals with running, training intensity etc...? But all in all, in most cases a good stable running shoe is more than sufficient. When you have a good shoe, the other factors from the Adidas study become more important: running too hard, on a too hard underground, for too long, far too often in a short amount of time will causes injuries no matter what shoes you wear.
Any final words?
Seasoned runners will generally disagree with my advice, but it isn't catered to them. Because if you're capable of running a lot and very often, chances are that natural selection decided you're a pretty good runner or else Mother Nature would have stopped you in your tracks long ago. This means that you get to wear lighter shoes or silly shoes like the Vibram ones, because you let your body do all the work. That's mainly where the performance enhancing comes from: leaving as much of the shoe out to not get in your way.
neutral meant as pun or only for technical meaning "no support such as inversion support"? This is extremely good answer (although a bit biased, not using word barefoot running but neutral -- perhaps the term "barefoot running" is too loaded term, neutral running sounds actually better agnostic choice). Anyway, it made me challenge my own running -style -- back to stone-age and adiadases to /dev/null for a while :P

In my (limited) experience, I find its better to go to a shop for advice on what shoes to buy than use my own judgement. In the UK, there are a range of shops called The Sweat Shop which have treadmills in the shops. They use these treadmills and slow motion cameras to analyse your running technique and advise you on the type of shoe to buy.
I thought this was a much better way of buying shoes than trying to find the shoes myself and they know what they are talking about. I'm guessing there are similar shops for our American cousins. So in summary, leave the choice to someone who knows that they're talking about.
My experience with running shoes is it's more important to replace them regularly than to worry yourself too much with some kind of marketing bs that manufacturers like Nike like to use to sell the shoes. A shoe with a lot of 'bounce' and flexibility in its sole that provides shock absorbence for your knees is best for running on concrete. Avoid the fashion house trainers and stick to Asics, New Balance, Mizuno as they're better value for money and made for runners instead of to pose in.
There's a trend with bare foot running now (this TED talk explains why), so you could save some dollars by grass/beach running instead!
All the options exist because running shoes are a very individualized item. Some people need more support in one area but not another while others need the exact opposite. Your best bet is to get a cheaper pair, use them for a time until broken in, and determine where you need to make improvements.
