Blisters are painful, fluid-filled lesions produced by friction and pressure. They can be caused by the following:
• Ill-fitting shoes
• Stiff shoes
• Wrinkled socks against the skin
• Excessive moisture
• Foot deformities
As blisters are a result of friction there are a number of simple techniques:
• Keep your feet dry
• Always wear socks as a cushion between your feet and shoes
• Wear properly fitting shoes
