Currently I'm running in the Structure 16 but I was looking for recommendations for other shoes to run workouts in. I have a pair of flats (Streak XC) that I'll wear towards the end of the season but I want to stick to trainers for now for durability. Does anyone have any reccomendations on anything Adidas, Saucony, Asics, New Balance or others? If it helps I'm looking to run sub 25 in the 8k.
