Fighting in period boots requires a change in footwork, that change produces better technique and a more grounded stance. The vibram soles allow you to cheat the history a bit as there is much argument as to what went on the bottoms of the soles of many boot's, shoe's, and sandals.
I fight exclusively in my vibram-soled Bohemond boots and found that for the first few months my form sucked and my feet hurt but I could tell within the first day that it would be better once I got used to the changes, and it did. This weekend I will be fighting a minimum of two days of three and I will be using my period boots the whole time.
Overall I'm much happier with these boots than with my USAF-issue combat boots.

EDIT: Yes Revival has new owners, I was PM'ed the news due to my involvement, though Chiv Bookshelf is still Brian's (and he has yet to return the publishing rights like promised). Strange to think I had something to do with that just by asking the right question at the right time.
