When Was The Last Time You Replaced Your Insoles? Yep, We Thought So — And Podiatrists Have A Warning

There’s nothing quite like the feeling of instant bliss you get while slipping into a pair of sneakers that truly supports your feet.

To achieve optimal comfort, it’s sometimes necessary to swap out the factory insole your shoe comes with for an aftermarket pair that’s more tailored to your unique foot challenges. The hefty price tag of some of these insoles can lull us into a false sense of security, leading us to think they’re nearly indestructible. But podiatrists say that’s a common misconception that can become a big pain — literally.

“If an insole has not been changed, it will break down and lead to misalignment, like a tire with uneven wear. They will no longer support the foot, leading to continued pain or compensation, altering the gait, and may lead to worse or new symptoms,” Dr. Keith Crenshaw, a podiatric physician with SoCal Foot Care, said.

So, how often should we be replacing our shoe insoles to achieve foot Nirvana? We consulted several podiatrists to find out and asked them to reveal some of the telltale signs that it’s time to toss your tired insoles. (Keep scrolling to read their insights on how often to replace these inserts, and what can happen when you don’t.) Ahead, they also shared some of their top picks for insoles that could give your feet relief.

Here’s what really happens when you don’t replace your insoles

If you can’t remember the last time you swapped out your insoles for a new pair, you could be unintentionally doing damage to your feet.

“Leaving insoles in too long that have effectively worn down can create situations of improper or inadequate support or cushioning that can lead to skin irritation or blistering, or overuse irritation of tendons and muscles reliant upon that support if it is inadequate,” Dr. Kirk McCullough, Medical Director at Fit:Match AI, said.

Foot misalignment and an exacerbation of pressure are two other potential issues.

“This can lead to Achilles strain, shin splints, bunion irritation, calluses and more,” Ferryanto said.

If you previously walked comfortably in your shoes but suddenly experience an uptick in pain, old insoles could be to blame.

“When an insole loses its structural integrity, it may no longer provide the same pressure relief or support. For someone who relies on that insole to manage foot pain, this can allow symptoms to return,” Barot said.

Lastly, failing to routinely replace your insoles can create another unpleasant side effect.

“Another problem is hygiene, especially with excessive sweating and wet winter footwear. This can be a bad combination with existing conditions like diabetes or reduced blood flow. If this is you, regular foot checks are advised,” Ferryanto said.

Sadly, there’s no universal replacement schedule

Dr. Bobby Pourziaee, a board-certified foot and ankle surgeon known as “The High Heel Doctor,” told HuffPost there’s no one-size-fits-all schedule for when you should replace your insoles. After all, it can vary based on a number of factors, including your weight, foot mechanics, activity level and frequency of use. However, there are some basic guidelines.

“For someone wearing the same shoes daily, I generally recommend evaluating their insoles every three to six months and considering replacement around six to 12 months, depending on their condition. People who spend eight to 12 hours a day standing, walking or working on hard surfaces may wear through their insoles considerably faster,” he said.

Runners, in particular, tend to do a number of their insoles.

“High-impact activities like running and jumping can increase wear and reduce the lifespan of the insoles. Those who are training for a marathon may need to replace their insoles about every three to six months,” Crenshaw said.

Meanwhile, pricier custom orthotics can last several years, according to Kunva Barot, a podiatric physician with 1Foot 2Foot Centre for Foot and Ankle Care.

“Although, their top covers and cushioning components may require replacement sooner,” he said.

But whe it is time to replace your insoles, there will be warning signs

Figuring out when to replace your insoles isn’t an exact science. But there are a few ways to tell when they’re past their prime.

“If you experience returning pain in the heel, arches, knee or back, these are signs to replace them. A simple ‘spring back’ test to check if the arches spring back after compression can determine if the inserts are still absorbing your activities,” Dr. Ersta Ferryanto, a podiatric physician with Weil Foot & Ankle Institute, said.

From an aesthetics perspective, any signs of cracks, flattened arches, thinning or worn fabric, or holes in the top cover are also signs to replace your insoles.
