Indo Boards are the perfect all around balance trainers for any sport where balance would be key, such as surfing, skateboarding, wakeboarding - in fact, any athlete would benefit greatly from Indoing! The learning curve is quick, and Indo Boards can be used by beginners to pros - there's always room to improve. There's various styles available for most boardsport needs, along with an excellent video for learning to cross step for longboarding, and learning Indo Board techniques.
The Original Indo Board consists of a wooden board and a roller. The board is shaped like an oval, with clear light grip on top (which can be used both bare foot or with skate shoes) and wood catches on the bottom tip and tail to keep the board from flying out from under you if you let it roll too far. The roller is plastic, ridiculously sturdy (it can easily handle 225 pound riders, and the video shoes guys using weights while riding!), with stripes of grippy rubber ringing it to help hold onto the board.
And that's it - these two parts, combined with your body, create a balancing situation where all three parts have to work together in sinc. This simulates other board sports, such as surfing, where you have to be aware of the moving wave, your moving board, and your own body. The same carries to any sport where balance is key.
