Yup they are. Actually the black ones were my first option but they were gone in my size, so I picked up these, also by 10 sei 0 otto:
But they are sized really big, my feet are 26 cms. long, which is a true 41, and I got 41 but they're a bit big even with an insole and medium socks. Unfortunately Vertice doesn't refund items on sale but they'd accept an exchange and I was considering picking up the burgundy ones and trying to dye them. I'm not really into burgundy boots.
