It has less to do with the female anatomy if the boots are set correctly and if the correct movements are used. Most of the women I see skiing or racing are cuff strong. Overpowered. I just finished completing an alignment on a FIS racer on Fischer boots last night. She was at Burke mountain for 2 years. No one addressed her boot issues. The exact same thing is happening to many world cup skiers.
The reason many women look knocked kneed and have a wide stance is that they have to get the leg out away from under their bodies to be able to push the boot and ski over on edge. This puts their balance on the inside ski, where they can't absorb or tighten the turn radius.
