Elan says the bevel helps prevent skiers from catching an edge while riding rails and boxes as well as landing jumps. The women's version of the Puzzle, it has a sandwich construction with a fiberglass-reinforced wood core. And it has a good amount of tip and tail rocker while staying pretty flat underfoot making it best suited for skiers who spend all their time in the park.
