We're getting a little far afield - seat too high is definitely an issue, but it's pretty rare I see anyone with a seat too high per se. I have little doubt that you see more women than men plantar flexing, because their crankarms are too long. We set the seat height so it's not giving us knee trouble by being too low at the top of the pedal stroke - but then, it's too high at the bottom of the pedal stroke.
