I'll be more to the point, if you have numbness, try first to lower the saddle. Too many people have the saddle adjusted too high or even ride on a frame that is too tall. You should not have to reach for the pedals with the foot and if you ride with the toe pointed down all the time, you may in fact be losing efficiency.

One other thing, make sure the saddle is level if you are a guy and slightly tipped down if you are a woman. For a guy to have his saddle tipped down, it will create more pressure on certain areas. Having it level will roll the pelvis back and relieve pressure.
