I've been searching for a replacement pair for myself since I get so much wear of these. I've had no luck for myself, but I've found quite a few pairs for friends who wear different sizes.
I've come across a blue and black pair, but no brown. If find a size 7 brown, please email me!
Not the same shoe, but I came across a very cute pair of pixie booties that I wanted to share in case anyone who wears a 7.5 would be interested. If the heel didn't have a zipper, I would have maybe considered purchasing them myself and using some inserts in the front and back.
