Understanding Foot Growth During Adulthood
For most people, the growth plates in their feet fuse and close during puberty, typically in the mid-to-late teens. This means the actual bone length of your feet is set for life. Therefore, a person who asks, "Can your feet grow at 28?" is not likely to be experiencing a genuine growth spurt. However, the sensation of feet getting larger is a very real phenomenon experienced by many adults. This apparent growth is caused by a variety of factors unrelated to skeletal development. Understanding these changes is key to maintaining proper foot health as you age.
The Role of Ligaments and Arches
One of the most significant reasons for apparent foot growth in adults is the wear and tear on the feet's ligaments and tendons over time. Like old elastic bands, the ligaments in your feet can lose their elasticity and stretch out over years of use. This process leads to the gradual flattening of the foot's arch. As the arch flattens, the foot lengthens and widens slightly. This structural change, known as adult-acquired flatfoot, can happen gradually and is a common cause of needing a larger shoe size later in life.
The Impact of Weight Gain
Carrying extra weight puts additional pressure on the feet's support structures, accelerating the process of arch flattening and widening. This increased pressure on the feet’s ligaments and tendons forces the foot to splay out under the extra burden. A study even found that people who underwent weight-loss surgery experienced a decrease in their shoe size. This demonstrates the direct link between body weight and foot size. Therefore, weight management can be a crucial factor in minimizing changes to your foot size over time.
Hormonal and Lifestyle Factors
Beyond aging and weight, other factors can influence foot size. Hormonal changes, particularly during pregnancy, cause ligaments throughout the body to relax, which can result in wider and flatter feet. Menopause can also contribute to changes in foot structure. Certain footwear choices, such as wearing unsupportive shoes or frequently walking barefoot, can also cause the ligaments and arches to stretch and flatten over time. Injuries, especially to the foot or ankle, can also cause permanent changes to the shape and size of the foot.
Medical Conditions That Alter Foot Size
In some cases, a change in foot size can be a symptom of an underlying medical condition. These conditions are less common but can be the cause of noticeable changes. It is important to consult a healthcare provider if you experience sudden or dramatic changes in foot size, pain, or discomfort.
| Condition | Effect on Foot Size | Related Symptoms |
|---|---|---|
| Acromegaly | Abnormal enlargement of hands, feet, and face due to excess growth hormone. | Joint pain, prominent forehead/jaw, fatigue. |
| Bunions | Bony bump that forms on the joint at the base of the big toe, pushing it inward. | Pain, swelling, redness at the joint. |
| Arthritis | Inflammation of the joints in the foot, causing pain, stiffness, and structural changes. | Decreased mobility, stiffness in joints. |
| Diabetes | Nerve damage (neuropathy) and swelling can lead to foot deformities and changes. | Numbness, tingling, swelling. |
How to Protect Your Feet as You Age
Fortunately, there are proactive steps you can take to minimize age-related foot changes and promote long-term foot health. These strategies focus on supporting the feet and addressing the root causes of widening and flattening.
- Wear Supportive Footwear: Choose shoes that provide proper arch support and a solid sole. Avoid wearing unsupportive shoes like flip-flops or high heels for extended periods.
- Use Arch Supports: Wearing orthotics or quality over-the-counter arch supports can help prevent your arches from flattening. A podiatrist can recommend the best option for your foot type.
- Maintain a Healthy Weight: Keeping your weight in check reduces the stress and pressure on the ligaments and tendons in your feet.
- Do Foot Strengthening Exercises: Gentle exercises can help strengthen the muscles in your feet, improving stability and supporting the arches.
- Get Your Feet Measured Regularly: Don't assume your shoe size stays the same. Have your feet measured every few years to ensure you are wearing the correct size and width.

Conclusion
While your feet's bones stop growing in your late teens, it is common for many adults to experience an increase in shoe size over time. The causes are not genuine growth but rather a combination of ligament laxity, arch flattening, weight gain, and lifestyle choices. By being mindful of these factors and taking proactive steps to support your feet, you can maintain comfort and foot health throughout your life. Listen to your body and adjust your footwear as needed to avoid pain and more serious conditions down the road.
