Hi there!
This is what I would do:
1. Determine what type of running foot do you have. Follow the link: http://www.runnersworld.com/running-shoes/take-wet-test-learn-your-foot-type;
2. Hit one of the best sport store in your area and look for those running shoes that have the sole made especially for your type;
3. Ask yourself how much do you want to spend on a good running shoes;
4. Do not buy cheap running shoes, they will hurt your legs in time.
