I just finished these the other day and I am very pleased with how they turned out. They are Angry Itch brand boots that I modified to fit into my post-apocalyptic/dystopian aesthetic.
The first thing I did was lightly stud the bottom straps. The leather is really thick so they warped a little bit but that’s fine. There were straps above but I took them off and hung some pandemic symbols from the rings instead. I bought the symbols off of Etsy and hung them from the outside ring with some jewellery wire that I wrapped around some clips. Finally, I coloured the white stitches with a purple acrylic paint pen. It is impossible to paint those stitches perfectly so I got some stray paint around them. Again, that is okay because my aesthetic isn’t based on a perfect appearance.
If you want to do some DIY work on a pair of boots I say go for it! It’s a lot of fun and you will be wearing boots that are unique to you.
