Nike Metcon 7 Women’s Fit Narrow Feet

Hi all! I was wondering if anyone could provide some guidance on the fit of Metacon 7 for women? I seen a post from a while ago where most people are saying they got a half size up, but no one specifies their foot width. I have a more narrow foot so sizing up seems like a bad idea. I recently tried on the newer Metcon 6s and found them too wide for me. I know the style of the shoe is different and that the 7s are discontinued so where I’d have to order them from would likely be final sale. Thanks for any help!!
