Understanding Shoe fitting changes
If you have been wearing the same shoe size for decades, there is a good chance your shoes no longer fit properly. The human foot undergoes significant changes with aging, and these changes can alter both the length and width of your feet. Research shows that most adults experience measurable increases in foot size after the age of 40, yet many people continue to buy the same size they wore in their twenties. Wearing shoes that do not accommodate your current foot dimensions can lead to a host of painful conditions that are entirely preventable.
One of the primary reasons feet get larger with age is the weakening of the ligaments and tendons that support the arch. The plantar fascia, the thick band of tissue that runs along the bottom of the foot, gradually loses its elasticity over the years. As this supportive structure loosens, the arch of the foot flattens and the foot elongates. This spreading can add a half size or even a full size to your shoe measurement. The loss of arch height also causes the foot to widen, meaning your shoes may need to be wider as well as longer.
The fat pads on the bottoms of the feet thin out as part of the natural aging process. These cushioning pads, which are located under the heel and the ball of the foot, absorb shock and protect the underlying bones and joints during walking. As the fat pads atrophy, the bones become more prominent and vulnerable to pressure, making hard or thin-soled shoes increasingly uncomfortable. This loss of natural cushioning is one of the reasons older adults often prefer shoes with more padding and support.
Hormonal changes, particularly those associated with menopause, can affect the feet. Declining estrogen levels contribute to a decrease in collagen production, which weakens the connective tissues throughout the body, including those in the feet. This hormonal shift can accelerate ligament laxity and arch collapse. Additionally, hormonal changes can affect fluid retention and may cause periodic swelling in the feet and ankles, making shoe fit inconsistent from day to day.
Weight gain that commonly occurs with aging adds mechanical stress to the feet and contributes to structural changes. Every additional pound of body weight translates to approximately three to four pounds of extra force on the feet during walking. This increased loading can flatten the arches, spread the forefoot, and exacerbate conditions like bunions and hammertoes. Maintaining a healthy weight is one of the best ways to slow the structural changes that alter shoe fit.
Signs and Symptoms to Watch For
Arthritis is a common condition that affects foot shape and shoe fit in older adults. Osteoarthritis can cause bony enlargements at the joints, particularly at the base of the big toe, which can make the foot wider and more difficult to fit into standard shoes. Rheumatoid arthritis can cause joint deformities that dramatically alter foot shape. Even mild arthritic changes can make previously comfortable shoes feel tight or painful in specific areas.
Circulation changes that occur with aging can also affect shoe fit. Reduced venous return from the lower extremities can cause fluid to accumulate in the feet and ankles, especially later in the day. This edema can make shoes that fit well in the morning feel uncomfortably tight by the afternoon. Conditions like chronic venous insufficiency and heart failure can exacerbate this swelling. Choosing shoes that accommodate some variation in foot volume is important for comfort and circulation.

Many older adults continue to wear shoes based on their remembered size rather than having their feet professionally measured. Studies have found that up to 65 percent of older adults wear shoes that are the wrong size, with the majority wearing shoes that are too narrow. This mismatch between foot size and shoe size is a significant contributor to foot pain, calluses, corns, bunions, and toenail problems in the aging population. Having your feet measured every time you purchase new shoes is a simple but important practice.
The time of day when you shop for shoes matters more as you age. Feet tend to swell throughout the day due to gravity and activity, and this swelling becomes more pronounced with age. Shopping for shoes in the late afternoon or evening, when your feet are at their largest, helps ensure that your shoes will be comfortable throughout the entire day. Trying on shoes in the morning may result in purchasing a pair that feels fine initially but becomes painfully tight by the end of the day.
Shoe construction and materials become increasingly important as feet age. Rigid, unsupportive shoes that might have been tolerable in youth can cause significant problems in older feet. Look for shoes with a firm heel counter to stabilize the rearfoot, a supportive midsole to compensate for lost arch support, and a cushioned insole to replace diminished fat pad cushioning. Shoes made of soft, flexible materials that can accommodate minor deformities without creating pressure points are also beneficial.
Treatment Options at Thrive Foot and Ankle
Custom orthotics can be particularly valuable for older adults whose feet have changed shape. These prescription inserts are molded to the specific contours of your feet and can provide the arch support, cushioning, and pressure redistribution that aging feet need. Orthotics can also accommodate deformities like bunions and hammertoes while distributing forces more evenly across the foot. When combined with properly fitting shoes, orthotics can significantly improve comfort and reduce the risk of foot problems.
Certain medical conditions that become more common with age can further complicate shoe fitting. Diabetes can cause neuropathy that makes it difficult to judge whether shoes fit properly, increasing the risk of pressure sores and ulcers. Peripheral arterial disease can make the feet more sensitive to pressure and less tolerant of ill-fitting footwear. If you have any of these conditions, professional guidance on shoe selection is especially important.
Having your feet evaluated by a podiatrist can provide valuable insights into how your feet have changed and what type of footwear will best support them. A comprehensive evaluation includes measuring both feet, assessing arch height and flexibility, checking for deformities, and evaluating your gait. Based on this assessment, your podiatrist can recommend specific shoe types, brands, and modifications that will accommodate your feet as they are today. Investing in properly fitting shoes is one of the most effective ways to maintain your mobility and comfort as you age.
