My son is a sophomore in high school and has been running for about 6 years. Do high school runners now a days have different shoes for speed days compared to their normal base days? Back when I ran a long time ago, everyone had one pair of running shoes and then spikes for races. He runs in Brooks Ghosts right now that he really likes and I was not sure if we should be getting him a different shoe like the Hyperion Tempo for faster days. Thanks
