Which of my running shoes should I wear today?

Choose the pair that suits today's ground and session, fits comfortably now and is in sound condition. If two of your shoes meet those needs, you can simply wear the one you fancy. Owning several pairs does not make every run a puzzle with one correct answer.

The useful question is what would make a pair a poor choice today. A favourite road shoe may be the wrong option for muddy paths. A shoe you love for short intervals may become uncomfortable on a much longer outing. Start by removing those mismatches, then choose among what remains.

What does this run ask of your shoes?

Describe the whole outing before looking at the shelf. Include the warm-up and cool-down in the distance, say whether the faster running is continuous or broken into reps, and check the ground. An 8km recovery run and an 8km session with fast repetitions can favour different shoes even though the mileage is identical.

Give particular weight to anything you cannot change on the route. If the path is muddy, a pleasant road ride does not settle the grip question. Salomon's terrain guidance distinguishes widely spaced, deeper lugs for mud from shorter lugs for firmer mixed ground. The specific outsole and conditions matter more than the word “trail” on the box.

Then ask what has worked for you before. You may already know that one pair feels comfortable for an hour and another is your favourite when changing pace. That experience is more useful than assigning every shoe a job from its advertising alone.

The same collection, three different mornings

This fictional runner owns a comfortable daily trainer, a lighter workout shoe and a trail shoe. All three fit and are in usable condition. The choices below follow their own experience of those pairs, rather than a claim that every shoe in each category behaves the same way.

Choosing from the same three owned pairs

Today's run	Pair to start with	Reason
6km recovery Dry roads	Daily trainer	Comfortable at a relaxed effort.
10km workout Roads	Workout shoe	Familiar fit and preferred feel for faster sections.
8km trail Muddy paths	Trail shoe	An outsole this runner trusts on these paths.

Change one detail and the decision can change. If the workout shoe is still soaked, the daily trainer may be an entirely satisfactory option for the workout. If the woodland route has become too slippery for the available shoes, changing the route is more useful than forcing a choice.

What if two pairs look equally suitable?

Use an ordinary preference to break the tie: which feels better at the intended effort, which is dry, or which you would enjoy wearing. Similar shoes can share runs. You do not need to ration every pair into an exclusive category.

Do a quick condition and fit check before leaving. A shoe's old role is less important than whether it still holds your foot comfortably and has the grip you need. Mileage and wear checks can help you keep that decision current; the total alone cannot tell you which shoe to wear this morning.

How to ask Cinda to choose from your shoes

Add your owned pairs to Rotation and check their run types, mileage and your feelings about them. On Home, open Running today? Let's pick your shoe. Choose Recovery for relaxed running, or Long, Workout, Race or Trail.

The follow-up depends on the session. Recovery and Long can include a distance; Long asks about its structure. Workout asks you to describe the session, Race asks the distance, and Trail asks about the terrain. You can add details such as wet roads or a pair to leave out.

“10km altogether on roads, with 5 × 3 minutes at a hard controlled effort. It is wet. Leave out my usual workout pair because it is still drying.”

That gives Cinda a more useful starting point than “pick my fastest shoe”. Its choice comes from the rotation you have supplied. Check the explanation against the actual conditions and how the pair feels on your feet. For help deciding whether your collection needs another pair at all, see the separate rotation guide.
