A good rotation is not about owning more shoes for the sake of it. It is about matching shoes to run types, spreading load, and knowing when one pair is doing too much work.
The planner
Most runners do not need a complicated system. A simple planner can keep daily trainers, speed shoes, long-run shoes, and trail pairs in the right lane.
Two-shoe setup
Even two shoes can share load well: one steady daily trainer and one pair reserved for faster days, wet days, trails, or longer efforts.
Three-plus pairs
A larger rotation can extend shoe life and sharpen feel, but it gets messy when shoe assignments are inconsistent.
Treadly workflow
Treadly helps you map run context to shoes, then keeps each pair's mileage and wear status visible as your training shifts.
List the kinds of runs you actually do in a normal week.
Assign one or more shoes to each run type.
Review mileage balance every couple of weeks and adjust the roles.
Two pairs are enough for many runners. More pairs can help when you run different surfaces, workouts, long runs, or races that benefit from different shoes.
