Blisters that prevent participation have been reported in almost half of endurance running events, including Triathlon. Although blisters are not a serious injury they can seriously affect your performance and prevent you from achieving your personal best. Blisters most commonly affect the heels, toes and balls of the feet. Blisters are formed by prolonged friction that produces a shearing force between the layers of skin. The layers of skin are forced apart and the space fills with blood or fluid, producing a painful blister.
Ensure that you have properly fitting running shoes and break these in gradually - never wear new running shoes for a long run.
Moisture Wicking Blister Socks with two layers are excellent for blister prevention. The inner layer stays with the foot; the outer layer moves with the shoe, reducing friction on the skin.
In elite level Triathletes who don't wear socks, friction can also be prevented with the use of an Anti Blister Stick. The lubricant reduces the friction that leads to blisters.
You have to ensure that the blister is cleaned thoroughly by a medical professional before it is lanced with a sterile implement. This can relieve the pressure and pain. Once the blister has been lanced it must be kept meticulously clean in order to prevent infection.
Blister plasters can help healing. They absorb fluids and maintain an important natural moisture balance. Skin cells are less likely to dry out and develop into a scab. This helps to form new, smooth tissue sooner.
