Yoga teacher's calf pain

Teresa Lovern

My yoga teacher is getting pain/cramp in his calves after a few minutes during every run.  He has been fitted correctly and his gait checked.  Is it possible that, as he is more flexible than most, he has got too much support from his trainers in his heels so its almost as if he's running on his toes more ?

thanks - I'll tell him.
