I won $100 from Asics towards a pair of shoes doing their treadmill challenge. I don't need any shoes for training, but I don't have any racing flats. I wear Saucony Kinvaras for pretty much all races, from 5k to marathon. Is it worth it to get racing flats for shorter distances, specifically 5-10K?
Are there any racing shoe recommendations for a runner who is a mild supinator? Or does that even matter when it comes to racing shoes?
