Getting more of an opinion poll on this topic. For most of my running life, I had one pair of training shoes that were used for everything. Finally in college I started changing shoes for tempos and track workouts but even then I just wore my same racing flats or spikes. Now, however, I have a pair of shoes for my daily mileage/long runs, alternate daily mileage/tempos, speed/hill days, and a pair of super shoes for races and key workouts. I've always been someone who enjoys trying out different shoes and seeing what's out there so the shoe rotation has been fun for me to try different models but part of me does miss the simplicity of just having a pair of running shoes that were for everything. Curious what others think about this. Do you have a big arsenal you rotate through or are you a one shoe fits all type?
