New running shoe question?

I run 1 hour 6 days a week and ive been running in pumas and it has always hurt my feet and knees so i decided to buy actual running shoes. I bought asics gel-ulus 12 and i totally screwed up and didnt go to an actual running shoe to see what kind of arch i have in my foot. The first 15 minutes my feet and knees started hurting and im wondering did i pick out the wrong shoe for me foot or do i need to just wear them in? Because i know your not supposed to wear new running shoes for a marathon but some people on here are telling me that good running shoes that fit to your foot shouldn't have to be warn in.
