Can anyone explain the theory behind the superwide stance?

The stance, itself, is slightly noticeable, but I think the way they get back to a normal standing position after each pitch (not batted or wild/passed) is what looks ridiculous and sticks out poorly - move each foot six-ten inches in, back and forth, until feet are normal width apart again = very jerky.

But not much sillier-looking by comparison, in my opinion, than navy, flat-front pants.

I have to use it for some of the adult women. If I happen to do FP or Co-Ed SP, there are some sort women that play in my area (one young lady is like 4'10", and I'm 6'1"). Heck, my partner one night was a guy who is 6'6", and he was hurting behind the plate!
