Blisters on the feet can be painful and uncomfortable, but there are several things you can do to prevent and treat them. Here are some tips from the search results:

Prevention:

• Wear moisture-wicking socks to prevent blisters on your feet.
• Wear comfortable, well-fitting shoes and clean socks to prevent blisters.
• Use padding to protect blisters in pressure areas, such as the bottom of your feet.
• Avoid wearing shoes or doing the activity that caused the blister until it heals.
• Minimize areas where friction may occur by wearing the proper fitting footwear, two pairs of socks, gloves, and padding the body in areas vulnerable to excess friction.

Treatment:

• Leave small, unbroken blisters alone as they will heal naturally on their own.
• Cover painful blisters with a soft dressing to cushion and protect them.
• If the blister does burst, dont peel off the dead skin. Instead, allow the fluid inside the blister to drain and cover the area with a dry, sterile dressing.
• Wash the area with warm water and gentle soap if the blister has popped.
• Apply antibiotic ointment to the area and cover it loosely with a sterile bandage or gauze.
• If the blister is in a pressure area such as the bottom of the foot, put a donut-shaped moleskin on it.
• Large painful blisters can be drained and treated by a trained professional.

Its important to note that blisters caused by a medical condition often can’t be prevented and need to be treated by a doctor.
