Some question Roy... why are you guys wearing Tabi boots? Does Sebukan Jujutsu have any connection with Ninjutsu?
Toribio Sensei does have some background in ninjutsu (I forget which 'kan'). More on him here.
The tabi thing isn't just for ninjas though, at lots of sword tournaments/embukai senior students (yondan and up) will often have tabi on. It's a bit more formal, and if you're sneaky, you can put some gel inserts into them so that you're not standing on hardwood all day..
