People ask me all the time for shoe advice, where to go, what brand is the best, etc. It is different for each person but there is no denying that for a runner, the absolute most important piece of equipment (unless you are a barefoot runner) are your shoes. They can make or break a run... in some ways I didn't realize how important it was to be 100% properly fitted to your running shoe. My first marathon I went into the Nike store and pretty blindly picked out a pair of shoes, they worked like a charm and so comfortable! Never blistered, never lost a toenail, both of which are pretty unheard of for marathon runners.
