    A non-degenerate differential 2-form on an even dimensional manifold M^2n is called an almost-symplectic structure. A necessary condition for the existence of an almost-symplectic structure is that all odd-dimensional Stiefel-Whitney classes of M should vanish. In this paper, we prove that all odd-dimensional Stiefel-Whitney classes of a smooth, closed, connected, orientable 8-manifold with spin structure vanish. We also study the almost-symplectic structures on certain classes of Spin(7)-manifolds.
