Volleyball shoes are very important because the bottoms of the shoes are specially made to help you not slip as much when on the court. This is to prevent the injury when going for a ball and you slip in fall. However, if you don't want to get volleyball shoes or even your volleyball shoes don't have that much traction, you can always just get the bottoms of your shoes wet and you won't slip either.
Whatever works for you is what you should do and not what everyone else does. However, if you're getting volleyball shoes, you may want to try women's Adidas volleyball shoes.
