Having been a serious runner for 45 years I can attest to the importance of not only a good fit but also a shoe suited for your particular gait and size. Running (and hiking) shoes are generally built with different lasts and structure based on four basic needs (styles); cushioning, stability, motion-control, and neutral. Suggest you visit a reputable running/hiking store, many of which have treadmills with video cameras so a gait specialist can tell you the best shoe for your needs. I particularly favor New Balance because they have a great business model and most of their high end shoes are made in the USA. Avoid the typical racing/crew shoe like the plague. I generally keep racing shoes behind the seat and don't put them on till I'm ready to get my racing pants on and they go right back behind the seat after a run.
