Ke$ha’s combat boots

Since I’m looking for some flat slouchy booties which also can be weared with bare legs, I came across Ke$ha’s heavily distressed combat boots. I think she totally rocks them, because she’s wearing them untied. So I’ve been looking myself for a pair just like these, but I can’t seem to find anything similar. Tips are absolutely welcome ;)

What do you think of her combat boots? 
Lots of love,
