Introduction
Plantar pain (pain in the sole of the foot) may result from the following causes:
- Excessive physical activity over a prolonged period can gradually lead to inflammation, resulting in pain in the sole of the foot.
- Wearing rigid-soled shoes or high heels frequently places increased pressure and tension on the plantar fascia and Achilles tendon.
- Individuals with obesity experience greater mechanical load on their feet during physical activity due to increased body weight, thereby raising their risk of injury.
There are four primary causes of plantar (sole-of-the-foot) pain:
1. Individuals who frequently engage in brisk walking or intense running may subject their feet to prolonged or excessive physical activity, leading to overuse and fatigue of the Achilles tendon and foot muscles. Over time, this cumulative stress can trigger inflammation and result in plantar pain.
2. People who habitually wear hard-soled shoes or high heels experience greater impact forces and reduced shock absorption while walking—placing increased pressure and tension on the plantar fascia and Achilles tendon. To mitigate this, it is advisable to select footwear with adequate arch support and thicker, softer soles to better absorb impact. Additionally, keeping a pair of lightweight, flat shoes or slippers at the office for occasional use can help relieve foot strain—a practical and beneficial habit.
3. Individuals with higher body weight—particularly those who are overweight or obese—are at increased risk. Their feet bear significantly greater mechanical loads during activity, and restricted ankle joint mobility further diminishes natural shock absorption, thereby heightening susceptibility to injury.
4. Older adults: With advancing age, the elasticity and flexibility of the plantar fascia gradually decline, increasing the likelihood of microtears during physical activity. To minimize injury risk, older individuals should perform thorough stretching before and after exercise and consciously incorporate foot-strengthening and flexibility-enhancing exercises into their daily routines.
