Blisters are one of the most common injuries suffered by runners. They may seem a minor irritation, but they can cause disproportionate discomfort and have a negative impact on performance particularly over long distances. At their worst they can result in intense pain, skin infection and even sepsis.
The literature on preventing blisters is a little disheartening. A systematic review of the prevention of friction blisters published in Wilderness & Environmental Medicine found there was limited evidence that socks, antiperspirants or barriers prevented blisters. But there was some evidence that paper tape may be an effective form of barrier prevention.
