I used to run in Nike Lunar Trainers . Nike ' s problem is that they are a fashiontrend company first that accidentally sometimes makes usable running shoes . If you find a shoe you can run 17 miles in without discomfort , I would buy as many of them as you can afford and more when they end up at the outlets . Nike completely redesigns or discontinues running shoes on an almost annual and sometimes semiannual basis . Even if they just update a shoe , they will often completely change the last or the way the upper fits and switch out the foam used such that it ' s an entirely different shoe from a runner ' s perspective . I will never run in Nike ' s again , but they almost seem to have a disdain for runners . but I do love some of the Nike Free line for daily use .
