Been looking into new racing flats, because I typically like to use them once a week for hard workouts on the track (Ex: Mile Repeats, 1-2 Mile Time Trials, 800's etc...). I don't like to use spikes just because I prefer the flat feel. I wet to a store and tried on the Flyinit Racers for fun because I heard they were very comfy and light. They definitely lived up to that. But I wondered would they be good for the workouts I do. Any opinion in that? The flats I've been using are Saucony Type A6 and they've been good but I just wanted to try something different. Any other shoe recommendations? All responses appreciated.
