Blistering can be a serious sports injury!
On the afternoon on June 30, 1924, Calvin Coolidge Jnr, the son of the 30th President of the USA, Calvin Coolidge, played a game of tennis with his brother John Coolidge.
Because he wore tennis shoes without socks, Calvin Jr. developed a blister on his right foot, which progressed into blood poisoning and was the cause of his death on July 7, 1924, less than three months after his sixteenth birthday. 
In 1994, blisters played a huge part in the loss by defending US Open champion Pete Sampras in the 4th round to relative unknown Jaime Yzanga.
Blistering of the feet was to plague Sampras for the remainder of his career. At the 89th Australian open in 2001, Sampras was again flattened by blistering, and again lost in the 4th round to the unseeded Todd Martin.
Whilst we often trivialise blistering, these 2 examples underline that it can be quite a serious sports injury, so it is worth delving into the causes and treatment in detail.
So.. why is it worth protecting the skin.. why is it so important?
