for your question. Blisters are often caused by prolonged friction from shoes that are not suitable for the foot or the physical activity. Heat and humidity can also aggravate the problem. To prevent blisters, it is recommended to choose shoes that are adapted to the foot or the physical activity. If a blister is present, a pad should be applied to protect it and prevent pressure points and rubbing. If the blister breaks, the wound should be cleaned, an antibiotic ointment applied, and the area should be covered with a bandage. Cushions that stick to the skin can be purchased at pharmacies. Additionally, thickening the socks or wearing them twice may help, but it may also make the feet hotter.
