Blisters

Causes of blisters

Friction from clothes or shoes is the usual cause of blisters, the repeated rubbing on the skin causing friction burns. This friction causes the outer layer of skin to separate from the inner layers and the space between fills with fluid.

How can an athlete prevent blisters?

• Wear correctly fitting shoes.
• Tape potential 'hot spots' by applying a protective second skin of plaster or tape.
• Ensure all seams on the inside of walking boots are flat. Take care of the boots, do not leave them on radiators or near heaters. This causes the leather to shrink and seams to protrude.
• Wet shoes, boots and socks will cause blisters far quicker than dry ones. Keep feet as dry as possible.
• Change socks as regularly as possible and use foot powder to help keep them dry.

At the first signs of a blister:

• The first sign of blisters will be redness over the skin, possibly at the back of the heel, the instep or toes.
• Apply a second skin dressing or blister plaster and tape the effected area.
• Ensure the feet are dry and change socks (unless you are in the middle of a race).

Useful products:

• Zinc Oxide Tape - Acts as a second skin to prevent friction
