Blisters on your feet are best kept intact and covered as much as possible while they heal. When you discover a blister, don’t “pop” it—simply clean it with soap and water. If it has already ruptured, try to leave the torn skin in place. After that, cover the spot with a bandage to protect it from friction. Making a donut bandage can alleviate the pressure on the sore, too: to do so, cut a hole the size of your blister in a moleskin bandage, then place that over the little wound. The thick moleskin protects your blister from pressure and friction without pressing against the sensitive bubble.
