flip flops

You might train in top-tier running shoes, but what about the shoes you slip on to grab groceries or commute to work? For runners, those “off-the-clock” shoes can quietly undo the benefits of smart training. Poor support or a bad fit can disrupt alignment, drain energy and even set the stage for injury, besides simply being uncomfortable.

Why bad shoes matter

According to podiatrist Miguel Cunha of Gotham Footcare, as reported by National Geographic, “your feet are the foundation of your body.” He explains that if casual shoes don’t support you properly, the stress shifts up the chain, into your knees, hips and back. For runners who already log high mileage, that added strain can mean slower recovery and nagging discomfort that transfers into painful workouts.

Everyday styles that trip runners up

Certain shoe choices make things worse. Flip-flops cause toe gripping, which tightens arches and calves. High heels throw body weight forward, overloading the forefoot and spine. Flat, unsupportive sneakers or worn-out slip-ons can stress joints and alter your gait. Even if only one shoe feels off, you may shorten your stride and overload the opposite leg—a recipe for imbalance that shows up the next time you hit the roads or trails.

How to spot shoe-related pain

Cunha recommends looking at your footwear itself for clues. Uneven wear patterns often reveal overpronation, where the arch collapses and the foot rolls inward. This can lead to plantar fasciitis, Achilles tendinitis and pain in the knees and hips. For a runner, those are injuries that can derail a season.

Choosing better daily shoes

The solution isn’t complicated: shop in person, get properly measured and prioritize support over style. (Consider buying running shoes or sneakers specifically for your everyday activities, and resist the temptation to run in them.) Cunha recommends brands such as Hoka, Brooks, Saucony, New Balance and ASICS. Even then, no shoe lasts forever, and take note of when your shoes start to wear out. Casual pairs of shoes should be replaced once the cushioning flattens or the tread wears down.
