This full-body workout machine is designed so that you don't have to be stuck in the gym on sunny days, but can instead enjoy an outdoor workout in the sun. With the D.C. aluminum rail, you have great flexibility: either enjoy a smooth ride with the 90 mm wheels and ILQ 7 bearings and be glad you skipped the gym, or later switch to 84 mm wheels for a more intense challenge. But don’t worry: thanks to our completely new upper material, your feet can always breathe well. The BOA system makes closing and adjusting super easy, allowing you to focus solely on skating, without exception.
