If your 8-year-old is just learning how to skate, training wheels can be an effective tool. Training wheels are a great way to improve balance and build confidence. Once your 8-year-old shows signs of progress they can also be utilized when practicing tricks. They limit any movement allowing more time to master the trick, and they can be installed and removed in seconds. Simply flip the skateboard over and pull the trainers over the wheels, when you are done you slide them off and you are on your way.
