I have the wheat version on it's way to me. Should arrive tomorrow. I tried the BP version last week, and while really cute, they are obviously for much higher volume feet than I have. I'm hoping this one will be better for a low-average volume foot.
BTW, I did find myself at DSW yesterday where I found the perfect-for-me black slide. Those came home with me.
As for the backorder, I would likely wait for the black since returns will start to be processed and ready for re-shipment soon.
