I really like the split sole look because they often come in a variety of sizes as well. I usually end up buying wide width shoes for women, but with split soles, they're soft enough to where I can pretty much fit into any of them.
And they actually look nice and elegant, unlike so many unfortunately clunky wide women's shoes. If you are a woman who needs wide width or split size shoes, then trying split sole shoes might be a good option.
They look classy, but they're pretty forgiving in terms of fit too.
