Do Feet Get Wider With Age? The Truth Behind Changing Shoe Sizes

It’s a common complaint: “I swear my feet are growing!” While your feet don’t actually grow in the traditional sense after your early twenties, they can indeed change shape—and yes, they often get wider and even longer over time.

The main culprit? Weakening ligaments. These rope-like tissues hold the bones in your feet together, providing structure and support. But as we age, years of standing, walking, and gravity take their toll. The arches of the feet can flatten, a condition sometimes called posterior tibial tendon dysfunction or simply age-related arch collapse. When this happens, the foot spreads out, making it both longer and wider.

Weight gain, pregnancy, and conditions like arthritis can accelerate this process. During pregnancy, for instance, the body releases a hormone called relaxin, which loosens ligaments throughout the body—including the feet—often leading to permanent changes in foot size. Many women find they need a larger or wider shoe after childbirth.

Even the type of footwear you favor plays a role. Years in unsupportive shoes or high heels can contribute to ligament strain and structural changes. Over time, this leads to that familiar feeling of shoes suddenly feeling too tight—even if you’ve owned them for years.

So while your feet aren’t “growing” like they did in adolescence, they’re definitely evolving. It’s not just in your head—you might actually need a new shoe size. The best defense? Supportive footwear, maintaining a healthy weight, and listening to your feet when they start to complain. After all, they carry you every day—treating them well can keep them more comfortable for decades to come.
