Heelys were launched back in 1999 and are now available in a wide variety of styles and colours. There are two main types of Heelys, One wheel Heelys and Two Wheel Heelys. Two Wheel Heelys are recommended for beginners, as they offer a little more stability and balance. One Wheel Heelys are perfect for riders with a little more confidence. The wheels is all Heelys can be removed, so can be worn as normal shoes.
