I invested in a pair of San Antonio Shoemaker sneakers a few years ago when I started having foot problems. They are still going fairly strong. Only change was a custom insole a podiatrist made for me. No foot problems since. Highly recommended getting quality shoes.

Going to have to disagree with this. Never cheap out on things that get between you and the ground. Mattresses, tires, and shoes are good examples. A good pair of shoes will last a lot longer and will be better for your feet and posture overal in my personal experience.
