Roger Bannister broke the four-minute mile in 1954

Bannister became the first man to run a mile in under four minutes in Oxford in 1954 - a feat that made him an international sporting celebrity.

Bannister had the shoes designed to be extremely light. He explained: "I could see there was an advantage in having the shoe as light as possible.

"The leather is extremely thin and the spikes are unusually thin, as I used a grindstone to make them even thinner.

"These shoes are the last tangible link I have with the four-minute mile. All my trophies are now on display at Pembroke College Oxford, where I was Master.

"They served me great purpose, I'm grateful to them. I think it's the right time to part with them and I plan to give part of the proceeds to the Autonomic Charitable Trust (ACT) which encourages the area of neurological research to which I have devoted most of my life."

A stopwatch used to time his run made £20,000 ($31,077) in May of this year.
