Ditto! I have size 10 feet, so I totally sympathize.
There are pointy shoes and pointy shoes. I, too, have a pair of Miu-Miu flats where the "slope" toward the tip starts kinda later (if you will, it's a shorter, squatter triangle, instead of an elongated one)--and that type of shoes is ok. I'm attaching a picture for exemplification.
A year ago, however, I got this pair of shoes in black:
They're the Hollywould "Bateau" style. Adorable, no? The black version was very classy and they fit well. But... they made my shoes look like bateaux. Boats, to be precise. They gaped a little unattractively at the sides, the pointy toe extended about 10 inches above my toe, it was a bad scene. Had to return them.
But, sales ***** that I am, I saw these again later, in coral (pictured) for...$39.95, back in the heyday of Zappos sales. Given that this was over 90% off, I couldn't resist (you will notice that they're still on sale now, but for an impossible price--
$265, down from $422). For $40, I was willing to take the risk again with a different color--and what do you know! The softer color, with a less pronounced contrast than the black and white, actually made a difference. These shoes are very comfortable and yes, well, maybe look a tad large, but not disgustingly so.
So, pick your battles when it comes to pointy toed shoes. You won't win all of them. But with some persistence, and if you keep trying on shoes, you're bound to find something you'll fall in love with and that looks really good on you.
