Sorry that you seem to have gotten so many off topic answers.
I would definitely recommend rotating shoes. It will help the shoes last longer and the differences in drop and cushion will help work different mussels.
Splitting your shoes up by pace is definitely a good way to do it. The adrenaline’s are a great easy and recovery shoe. Some shoes I’d recommend for faster days/workouts are:
-Saucony endorphin speeds (great cushioned, light, plated shoe, feels fast)
-NB rebel v2 (light, fast, responsive, very soft cushioned though)
-Reebok float ride run fast (little more minimal but great responsive shoe, can be found for cheap)
-Adidas Boston 8/9 (i haven’t tried the 10)
If you have the chase I’d recommend trying them on before you buy so you can get a feel for what you like and fit.
