There's a few "fighting road" japan gloves on sale on ebay. Rare to see them, so if you are interested better act fast!
Bodymaker in Japan makes them. They don't ship to the States though. Gotta find a friend to help you out.
Those are not a discontinued product.
You can still buy them direct from Fight Road's website, although you will be paying for shipping from Japan. And if I remember correctly, these are what Pancrase still use (although, I think I remember them being called "victory road"?).
PRIDE had numerous manufacturers. There is a collector who has around 10 of the first prototypes which included versions made by many of the companies mentioned above, Ouano, Thunder, Bodymaker, Winning, etc.
They do not sell them on their website but Bodymaker is the producer of the DREAM and PRIDE gloves, although they don't look to have a lace up version available to the public.
World Victory Road was the company behind the Sengoku promotion. Maybe that's what you're thinking of?
