Yes, you can carve on a longboard with soft wheels. Soft wheels provide more grip and better shock absorption, making them suitable for carving on various surfaces. They offer a smoother ride and are more forgiving on rough or uneven terrains. However, keep in mind that softer wheels might provide less slide for aggressive carves. It's important to choose the right durometer (hardness) of wheels based on your preferred style of carving and the type of terrain you'll be riding on.
