saw similar looking ones on shopbop awhile ago from tashkent by cheyenne... but i just looked on shopbop there arent any like those ones anymore. there is a similar one on the tashkenynyc.com website...
Those are a variation of the J Cole Boot by Tashkent By Cheyenne. J Cole Boot
There are several different eras of the Cole boot and the ones that Julia is wearing is one of the first designs. As you can see from the link above the J Cole has the cutouts on the front of the shoe and there's another design called the Cole Platform Wedge.
I own both types and they are incredibly flattering and I get compliments on them all the time.
