Slide board for use on snow having in proximity to one of its front and/or rear ends, a point of maximum width located beyond the front and/or rear contact line, beyond which the board upturn is defined, said board comprising an internal structure including: a core extending over the greater part of the board; and at least one mechanical reinforcement layer lying directly or indirectly on said core, extending inside the board upturn beyond the front and/or rear contact line, wherein at least one of the reinforcement layers has an extreme longitudinal point located at an intermediate level between the contact line and the extreme point of the board upturn, and wherein in a zone defined between the contact line and the point of maximum width, said reinforcement layer has a total cross-section, measured in a plane perpendicular to the longitudinal axis of the board, which decreases overall moving towards the extreme point of the board upturn.
