Blisters on the feet commonly form due to friction, often caused by tight or new shoes that rub against the skin. This friction creates a pocket of fluid under the skin, leading to the formation of a blister.

Another common cause of foot blisters is wearing wet socks, which increase friction and moisture, making the skin more prone to damage. Synthetic socks, which don’t allow the feet to breathe as well as natural fibers, can also contribute to blister formation.

In addition to these external factors, certain health conditions can cause blisters on the feet. Contact dermatitis, a skin irritation, can lead to blisters when the skin reacts to allergens or irritants. Fungal infections like athlete’s foot can also result in blistering, as can conditions like dyshidrosis, a type of eczema that causes fluid-filled blisters on the hands and feet.

To prevent blisters, it’s important to wear properly fitting shoes, choose moisture-wicking socks, and address any underlying health conditions that could contribute to blister formation. Proper foot care and attention to footwear can help reduce the risk.
