Tendonitis in foot

I have pretty severe pain running along the outside of my right foot which is worse depending on my shoes. I always wear athletic shoes. I’m just wondering if there is a stretch for that and if there is a specific brand of tennis shoe that you recommend. I have a wide foot but sometimes even with wide shoes I can feel the line where it narrows in the center of the foot.
