5 Things in Your Closet You Need to Throw Away Now (Your Underwear, for Starters)

How long it takes for your athletic shoes to break down depends on how you use them. “If you’re running in them, your shoes need to be replaced approximately every six months,” says Miguel Cunha, DPM, podiatrist and founder of Gotham Foot Care in New York City. If you wear them mainly as comfy walking shoes and not for athletics, Dr. Cunha says every 10 months is about right. Ultimately, they’re designed to last about 400-500 miles, he adds.

Not wearing kicks with proper support or if the shock absorption has worn down puts you at risk of foot and leg injuries. So give your sneakers a good once over. "Shoes are no longer wearable if the heel is more worn down on one side compared to the other, causing the shoe to lean on one side," Cunha says. If your pair is still in decent shape but needs a cleaning, he suggests using a gentle soap, cold water, and then air drying. "The heat from a dryer breaks down the glue and destroys your shoes," he warns.

To replace: Check out APL's TechLoom Breeze Knit sneakers. They're easy to slip on and off, and the knit uppers are ultra-comfy.

The typical pair of undies can last up to a couple of years. But they can also fall apart faster than that—wear and tear from constantly being tossed in the washer and dryer could degrade the elastic or make them less stretchy. If they’re not supportive or just don’t fit right anymore, they’re probably not comfortable…and it’s time to junk them.

If the fabric shrank or your body changed shape and they’re now too tight, that’s another reason to throw them out. “If your underwear is too tight, you can cause vaginal and vulva irritation,” women’s health expert Jennifer Wider, MD, previously told Health. That’s especially true for thongs; if the fabric wedged in your butt checks is too tight or irritates you, a skin infection could result—so chuck and replace.

To replace: We are fans of Cosabella 'Never Say Never' undies. While not cheap, they manage to hold their shape exceptionally well, even after multiple washes.

There’s a reason why bras are categorized as delicates. “Even when you’re treating your bras like gold, most start to lose their shape, support, or elasticity at around six months to a year depending on the frequency of wash and wear,” explains Reebok’s senior Innovation apparel designer Danielle Witek. “Water, detergent and heat will start to destroy the structure of a typical bra.”

The general rule is that a bra can last about a year, but that also depends on how many you have in your rotation. So give them a close look: Notice any frayed edges, exposed underwires, or if the straps or band have lost their elasticity. Even if the bra itself seems to be in good shape, toss it if body or breast size changes have made it more or less supportive. Wearing the wrong size bra can result in skin irritation and back and neck pain.

To replace: Swap stretched-out supporters with the Calvin Klein Perfectly Fit Lightly Lined Memory Touch T-Shirt Bra, which might just be the perfect T-shirt bra. We love the supersoft stretch fabric, the wide range of sizes and colors, and that there's just enough lining to deliver coverage without feeling bulky.

The average sports bra can last anywhere from 6 to 12 months depending on how often you wear it. When it can no longer support you and/or feels uncomfortable during a workout, retire it. "Over time, elastics and spandex materials begin to break down pretty quickly with continuous wash and wear," Witek says.

It’s not just normal wear and tear that can degrade the fabric of your sports bra but any changes in body or breast size. "Be sure you're checking in with the fit of your sports bras every few months to make sure they're snug under the bust, throughout the straps and across the center of the breast," she advises.

To help them last longer, Witek suggests hand-washing. "Take a day to wash them all by hand with a gentle detergent and hang dry," she says. The lack of heat and harsh chemicals will keep the garment intact for a longer period of time. If that seems to labor intensive, at least ditch the dryer and let them air-dry instead.

To replace: When in doubt, we reach for the stretchy Champion Freedom Seamless Racerback Sport Bra, which delivers moderate support, is moisture-wicking, has a seamless design to keep chafing at bay, and comes in a slew of solid, versatile colors.

“Once the socks have a hole from wear and tear, then it’s time to replace it,” says Cunha. That might sound like a no brainer, but it’s easy to forget about a hole by the toe or on the heel…until the lack of support ends up giving you a blister, callous, or other foot skin injury. Even if your socks aren’t battered, consider a refresh after a year. Socks, especially athletic socks, can lose their cushioning and shape by about that time, and considering how much sweat socks absorb when you’re active, they may not be looking or smelling all that great anyway.

To replace: One Health editor has raved about Balega Hidden Comfort No-Show Running Socks, her favorite socks to run in. "The plush sole makes these the cushiest socks I've ever slipped on, but the mesh upper construction keeps them from feeling hot or heavy," she says. And she's not alone: Over 6,000 Amazon customers have given the socks a five-star rating.
