These boots were sold back in 2008 by the fine folks at Rockahula. There was no mention of how much they were sold for, but I'd definitely pay a pretty penny if I ever came across these.
It's no secret the Road Champs are an original pattern inspired by early American boots, but it's possible Christophe ran across a similar pair during his 2 1/2 years of research and development. His work clearly paid off...
