Summer conditions, including fluctuating temperatures and constant exposure to air conditioning, can worsen skin dryness. Heels, which support a large portion of body weight, are particularly susceptible to thickened skin, calluses, and cracking caused by moisture loss and the buildup of dead skin.
Dr. Yugeun Kim, an orthopedic surgeon at Bupyeong Himchan Hospital, cautions, “Ill-fitting shoes or those lacking proper shock absorption can significantly increase the risk of foot disorders. Choosing well-fitted shoes with soft insoles and proper cushioning is essential for maintaining foot health.”
Foot Disorders Linked to Improper Footwear
Common foot conditions tied to such footwear include hallux valgus, plantar fasciitis, and interdigital neuroma.
Hallux valgus, commonly called a bunion, occurs when the big toe angles toward the second toe, causing the joint to protrude outward. Persistent pain or visible bulging at the big toe’s base may signal this condition. It is more prevalent among women, often caused by wearing tight, pointed-toe shoes or high heels.
Plantar fasciitis is an inflammation of the plantar fascia—a thick band of tissue that runs along the sole—typically caused by repeated stress or microtrauma. Symptoms include sharp pain with the first steps in the morning or after prolonged sitting. Wearing thin, unsupportive footwear or walking for extended periods can increase the risk.
Interdigital neuroma, also known as Morton’s neuroma, results from thickened tissue around nerves between the toes, causing pain and numbness. It often stems from wearing flat, rigid-soled shoes or those with narrow toe boxes. Because symptoms often ease when footwear is removed, many individuals may overlook or delay diagnosis.
Calluses and Cracked Heels: Indicators of Foot Stress
Calluses and thick, dry skin are more than cosmetic concerns. They develop from repeated friction or pressure and, in severe cases, can lead to inflammation or infection. Calluses often recur unless the underlying cause—typically improper footwear—is addressed.
To manage calluses, soak your feet in warm water to soften the skin, then gently exfoliate with a pumice stone or specialized foot file. Overzealous or frequent scrubbing can cause abrasions, increasing the risk of bacterial infection, so moderation is essential.
The heel area, which naturally has thicker skin to absorb pressure, is particularly prone to dryness in summer due to indoor air conditioning. If left untreated, cracked heels can become painful and inflamed. Applying foot cream or lotion once or twice daily is essential for prevention.
Strengthening Foot Muscles for Optimal Health
Proper footwear helps prevent many foot problems, but maintaining strong foot muscles is equally important. When purchasing shoes, measure both feet and select a size that accommodates the larger foot. Choose styles with a rounded toe box, low heels (preferably under 5 cm), soft uppers, and well-cushioned soles.
“The feet are essential structures that support us throughout life,” says Dr. Kim. “Even minor foot pain or deformities should not be ignored. Simple exercises, such as toe spreading and flexing, help strengthen the intrinsic foot muscles and significantly lower the risk of developing foot disorders.”
A simple way to assess foot strength is by checking if you can spread your toes at least 5 millimeters apart. Inability to perform this movement may indicate weakened muscles or other underlying conditions. Regular toe-spreading exercises can be an effective strategy for preserving foot strength and function.
