An amazing story about actions over words in NYT:

Surreptitiously, Mimura made soles of two slightly different thicknesses, to compensate for the fact that Takahashi’s left leg was eight millimeters — about a third of an inch — longer than her right leg. She had tried a pair of the uneven soles before the Sydney Olympics, but felt uncomfortable.

Still, Mimura felt Takahashi needed such shoes to win and to avoid a recurrence of pain caused by the disparity in her legs. Without Takahashi’s knowledge, Mimura gave her the uneven soles, then wrote a letter of resignation, in case she failed to win gold.

“I decided to take full responsibility because I made this pair against her wishes,” Mimura said of the letter. “I didn’t have to hand it over. It’s still in my desk.”
