I cant stress enough about the right shoe for you!!!! I had some chronic knee issues and started developing some hip pain. I had a "good" pair of Saucony running shoes....however when they were getting worn I went to actual running shoe store and had my gait analyzed.....turns out my Saucony were the completely wrong shoe for me. I've since been running in my Mizuno's and after the second run my knee and hip pain were gone!! Certainly made me a believer!!
