I am happy to say we finally invested in commercial-grade tatami mats for the Dojo. Our previous 1" puzzle mats were excellent, but I wanted to move up to this top grade since so many students train on them.
The new ones are ZEBRA 6'-7" x 3'4" x 1.5" thickness. They have a light rice-straw texture for grip without tearing up your feet during hours of training. www.ZebraAthletics.com Check out their "About Us" tab and see whom all they serve as partners. These mats will serve us in karatedo, kobudo, takedowns and grappling, and yoga!
In karate, we have to protect our feet. The constant pounding and friction are hard on them. I love training on wood floors, but they can be too hard unless the subfloor has spring. Our subfloor is concrete.
Happy to have these!
