It all began as a nice gesture from a fan
Years ago – we’re talking back in the 70s – Takei received a pair of running shoes from a fan that the actor subsequently wore on a 10k run.
After the run, Takei’s right foot “got the most horrific cramp and all the muscle on my right side cramped up”.
He tried to have it fixed
Takei had surgery to correct the damage, but after a short while the foot returned to its (now permanently) curved state.
