While I agree with macski about sitting on a butt-o-meter at a bike shop, there are a handful of women on this board who have sit bone measurements off the edge of statistical normal. For us, it is a Brooks B68 or nothing.

Most bike saddles at that width are poofy tractor saddles. As a vegetarian that leans vegan I couldn't bring myself to go leather. But, after too long and too many wasted saddles, I bought a B68 and never went back.

Wallbike has a generous try it and return it policy on any Brooks saddle. They're expensive, but worth it.
