The Zippy is a traditional style balance board addressing the balance training needs of the entire family. With its outrigger roller design, riders can experience reduced, toe to heal transitions thereby making The Zippy ideal for beginner to intermediate riders of all ages. The longer Zippy rock is machined with our patented outrigger design which act as "training wheels" when a rider applies toe or heal pressure to the board. The outriggers allow for increased stability when performing maneuvers requiring toe and heal pressure such as turning spinning and tilting. It's the outrigger design that makes the Zippy ideal for beginner to intermediate riders. Conversely the outrigger-less design of the Flow rock allows the rider to achieve greater toe and heal performance at higher angles thereby making the Flow more challenging and performance driven. The Flow is ideal for intermediate to advanced riders.
