Super outfit!
About the cheap boots, I bought inexpensive vinyl Funtasma boots for my Allan Quatermain costume. On YouTube I found a how-to video on how to paint them to create weathered Jedi boots.
I did it using ordinary Liquitex paint.
I've had those boots for a few years now, I've worn them for a number of different costumes. The paint hasn't come off despite all the wear they've gotten.
Also they're very comfortable! I've spent many long days at Cons and my feet are happy.
Here's how they came (ugly brown vinyl), stippling reddish brown over the dark brown, then drybrushing "dust" or "wear", and how they look with one of my costumes.
Here on the right is my first attempt, doing more subtle weathering, with Quatermain.
But I saw that it was too subtle to show up well in photos, so I did the more extreme weathering seen above. It "reads" better in photos though it might be a bit over-the-top.
Here it is with a Jedi and Ser Barristan
