I know a woman who got so bad on a Brooks riding PBP that she took 6 months to heal. Yeah, it's a real thing. Gotta have the cutout. I also rode a Superflow and also got sore sit bones which didn't seem to get better with use. My wife went to a Selle Italia Diva Gel Flow, not the Superflow. It looks just like the men's MAN saddle but very slightly different shape. Works for her and other women with whom I ride, no apparent time limit. The slot is obviously smaller, but good chance it'll work. Everyone's different.
