Boot clips almost look like they require modification to the boot? I didn’t look hard, but didn’t see an explanation of how they work.
I have a pair of brown croc boot crowns. I have very hard to fit legs, but some off the rack black boots work for me. I mostly wear brown, but have a black dressage coat, and that combined with black boots and brown croc boot crowns will work nicely if I feel like it. For multiple day shows where it’s pretty toasty I may pull out the black for day 2 to avoid sweaty filthy jackets.
I can also use the brown boot crown on the brown custom boots I’m ordering if I want that top. It goes with my bridle and saddle, so I likely will at times!
