I am looking into getting new shoes to train in. I need a pair of everyday mileage shoes and a pair of shoes for interval work. I am looking at the Pegasus for the former and the Streak 7 for the latter. I am wondering if it is a good idea to train in the Streak 7 as well. I currently have relatively new Hokas and hate them because they dig into my right foot giving me painful blisters. I will not be getting Hokas again but they are very cushioned and the Streaks are not as cushioned. This makes me worry that the transition will be difficult. Should I just use the Pegasus?
