Key Takeaways
- Running shoes typically last 300–500 miles; new aches are a strong signal they are done.
- Sports bras usually last about 6–12 months with frequent use; check band, straps, and bounce.
- Leggings have no fixed lifespan — replace when they go sheer, bag out, or stop staying up.
- Cold washing, no fabric softener, and air-drying extend the life of all activewear.
- Rotating pairs spreads wear and makes each item last longer.
How long should a sports bra last? When are running shoes really done? Activewear gets heavy use, constant washing, and lots of stretch — but the 'replace every X months' rules you hear can feel suspiciously convenient for brands. The honest answer is that it depends on use and care, but there are clear signs to watch for.
Fast answer
Shoes: 300–500 miles. Sports bras: ~6–12 months of regular use.
Leggings have no fixed lifespan — replace them when they go sheer, lose stretch, or stop staying up.

Running shoes
The common guideline is 300–500 miles. Heavier runners, harder surfaces, and soft max-cushion foams tend toward the lower end; lighter runners and firmer shoes can go further. The best signal is your body: new aches in your shins, knees, or feet after runs in an older pair often mean the midsole has broken down. Rotating two pairs can extend their life.

Sports bras
Sports bras work hard: the band and straps stretch and rebound thousands of times per run. Signs it is done include a band that rides up or feels loose on the tightest hook, straps that will not stay put, more bounce than before, new chafing, or a stain or odour that will not wash out. A high-impact bra that has lost support can be demoted to yoga or walking. Shopping? Start with the best sports bras of 2026.
Leggings
- They turn sheer when you squat — the fabric has thinned. Check with our squat-proof test.
- The knees or seat bag out and do not recover after washing.
- The waistband rolls or slides when it used to stay put — see why leggings roll down.
- Heavy pilling on the inner thighs.
- Seams are fraying or splitting.
Make everything last longer
- Wash cold, inside out, and skip fabric softener.
- Air-dry — heat is the biggest enemy of elastane.
- Hang sweaty gear to dry before it goes in the hamper.
- Rotate between two or three pairs or bras.
- Separate activewear from heavy items like jeans and towels.
Full care details are in our leggings washing guide. When you do retire activewear, check for textile recycling or take-back programmes rather than binning it.
Frequently Asked
How often should you replace your sports bra?
With regular use, roughly every 6–12 months. Replace sooner if the band stretches out, straps slip, you notice more bounce, or it starts to chafe.
How many miles do running shoes last?
Typically 300–500 miles (about 480–800 km), depending on your weight, running surface, and the shoe's foam. New aches after runs are a good signal it is time.
How long do leggings last?
There is no fixed timeline. Frequently worn pairs may last a year or two; well-cared-for pairs can last much longer. Replace them when they become sheer, lose shape, or the waistband stops holding.
How do I make my activewear last longer?
Wash cold and inside out, avoid fabric softener, air-dry instead of tumble-drying, let sweaty items dry before washing, and rotate between multiple pieces.
