Question: Running Shoes

When I started to run, I realized that flip-flops were not the answer to my running needs. I just happen to have a pair of Saucony running shoes from an outlet mall and I use them to this day. Since I am in need of a new pair of running shoes, my question is which shoe should I buy? What do you look for in a running shoe?

I will probably go shopping for a pair this weekend, so leave a comment and let me know your thoughts.
