Blisters

Most blisters on the feet are a result of heat, foot perspiration and friction and do not require medical attention. 
The sock and the foot then rub against each other and the inside of the shoe.
Fluid fills up a space between layers of skin to protect the area.

New skin will form underneath the affected area and the fluid built up in the blister is absorbed back into the tissue.

Do not remove the skin over a broken blister. The new skin underneath needs this protective cover.

Blisters can "pop" by themselves and become infected, filled with white or yellow fluid.
Do not ignore redness or leaking yellow liquid and red lines near the blister.
