Shoe Health tracks the mileage and wear of each pair of running shoes. As runs import from Apple Health and you assign them to the pair you wore, that shoe accumulates its own distance and a wear picture you can actually rely on.
What it tracks per pair
- Total mileage — built from the running distance of every workout you assign to the shoe.
- Per-shoe statistics — distance, pace, and duration, so you can see how each pair is actually used.
- A wear level — a running view of how far through its life a pair is.
- An estimated retirement point — based on its mileage against its lifespan.
How wear is calculated
A shoe’s wear is based on its total running distance. When you add a pair from the built-in catalog, a suggested lifespan tuned to the shoe’s foam and category is pre-filled — and you can adjust it any time. Add a pair manually and you set the lifespan yourself.
That gives you a consistent, per-pair number instead of a vague memory of “these feel a bit flat.”
Mileage is a signal, not a verdict
Distance is the earliest and easiest signal that a pair is aging, but it isn’t the whole story. Two pairs with identical mileage can be in very different condition depending on your weight, stride, the surface, and the foam. Shoe Health makes the mileage accurate and visible so you can weigh it against how the shoe actually looks and feels — the physical wear signs that tell you when to replace matter just as much.
Why it matters
Accurate per-pair mileage is what makes everything else work: a balanced rotation, well-timed replacements, and knowing which pair is quietly doing too much of your training. It’s the difference between managing your shoes on purpose and replacing them in a panic.
