I started out with a Cumulus 10, but was having a bit of joint pain in the outside of my knee. I really like the feel of Asics, so I decided to try something with a bit more support. I could IMMEDIATELY feel the difference. I had to be careful at first because it worked my leg in such a different way. I noticed much more muscle fatigue on the inside of my calf, indicating that this shoe was adjusting my foot outward to correct for the pronation.

If you are having leg pain, do yourself a favor and go to a real running store where they can video you running on a treadmill. They can diagnose your gate and tell you which shoe might work well. Don't do what I did and just start buying shoes. I ended up with a pair of Cumulus that I hardly used. Not wanting to have that shoe go to waste I ended up spending more money for a corrective insert. Now they work fine, but I could have saved myself a chunk of money.

Oh, and the cool yellow stripes make me run faster. I'm sure of it!
