As a health and wellness expert with a focus on musculoskeletal health, I can provide you with a detailed understanding of the factors that can influence the growth and changes in your feet over time.

Firstly, it's important to understand that the human body, including the feet, is subject to the natural process of aging. This process can bring about changes in the structure and function of various body parts. When it comes to the feet, one of the key factors that can contribute to their growth or change in size is the degeneration of the tendons and ligaments that provide support and structure to the foot.

The statement that "Feet do get bigger over decades of pounding" is not entirely accurate. While it's true that feet can change in size, it's not necessarily due to the physical pounding or the impact of walking and running over time. Instead, the growth or change in size is more likely related to the loss of elasticity in the supporting structures of the foot. As we age, the tendons and ligaments that help to maintain the foot's arch can lose their elasticity, leading to a flattening of the foot.

This flattening effect can make the foot appear larger or cause it to measure a larger shoe size. It's been observed that some people over the age of 40 may experience an increase in shoe size, potentially gaining half a shoe size every 10 years. However, this is not a universal rule and can vary greatly from person to person.

The elongation of the tendon along the length of the sole, as mentioned, can contribute to the lowering of the arch. This is a part of the natural aging process and can be influenced by a variety of factors including genetics, overall health, and lifestyle choices.

It's also worth noting that other factors can influence the size and shape of the feet. These can include:


1. Weight: An increase in body weight can put additional pressure on the feet, potentially leading to a flattening of the arch and an increase in foot size.

2. Diabetes: Certain health conditions, such as diabetes, can affect the nerves and blood vessels in the feet, which may also contribute to changes in foot size.

3. Pregnancy: Hormonal changes and water retention during pregnancy can cause temporary swelling in the feet, which may result in a need for a larger shoe size during that time.

4. Ill-fitting shoes: Wearing shoes that are too tight or too loose can also affect the shape and size of the feet over time.

In conclusion, while it's possible for feet to change in size over time, this is typically due to the natural aging process and the loss of elasticity in the foot's supporting structures, rather than the physical act of walking or running. It's important to monitor any changes in your feet and consult with a healthcare professional if you notice significant changes or if you have any concerns about your foot health.
