That's very nice of the instructor, to show off his neat shoes... while everyone else gets numb toes.

my favorite one is actually one of the few in his class who does NOT use special shoes in a sort of down-to-earth approach. I am fortunate that all bikes have spd pedals, except when I called them before first attending, the dolt on the phone said no, they did not have hem. And it is quite a flashy new club too. just the employees are... well... (this does not apply to my fave instructor)
