The Daily Mail has an interesting little piece about Asics developing a running shoe aimed at women that "adapts to suit (our) hormone levels."
Ok. Asics? WTF? (sigh) Look I'm really glad you're studying women more closely, seeing as how we're a rapidly growing segment of the running population. It just seems like good business sense. But, you are falling for the classic "women and their hormones" crap. I mean really. A shoe designed to change when I'm fertile and when I'm not? Weird. Unnecessary. I have NEVER noticed a change in my arch when I run during that time of the month. Exhaustion? Yes. Could you find a way to attach a caffeine drip from the shoes to my mouth? That would be more useful. Irritability? Yes, in spades, and this isn't helping. It's just absurd and expensive. You're just trying to bilk us out of money aren't you? Don't men have hormones? Pretty sure they do. Do they need changing arch support for their special times too?
Ok Asics- take a page from Saucony's R&D department and make something useful. 
The Razor is awesome. It is the only completely waterproof running shoe I know of and running on sloppy-ass Chicago trails it has proved itself indispensible. I can wade into an ankle deep puddle in these suckers. Or three inches of snow. That is useful. Hormone concerns belong with my birth control providers. Not my running shoes, thanks. 
(this is what I have to deal with and it gets my hormones all cuuuurrrrazy-like!)

If companies REALLY want to capitalize on That Time of the Month, they need to start renting out villas on Bora Bora, where it's cozy and tropical and you're totally alone except for a superfast internet connection and all of the chocolate you'd care to eat. Oh and wine. Wine is good, too.
Of course, it's not like I've given this any actual thought or anything.
I used to wear asics until I figured out they were making my gait worse instead of helping it. Oops! Changed shoes and my running has gotten much easier. :)
