A snowboard comprising a board on which two bindings are mounted on the board's surface at a distance apart approximately corresponding to around 1/3 of the board's length, where the board is designed with inwardly curved edge portions, the board having greater width at both ends at the transition to the tips (A-A) than at the middle (B-B), with upwardly curved tips ( 3,4 ), possibly with a slightly more moderate tip at one end, or skis comprising a ski on which a binding is mounted slightly behind the middle of the ski, where the ski is designed with inwardly curved edge portions, the ski having a greater width at both ends at the transition to the tips (A-A and C-C) than in the middle (B-B), with upwardly curved tips ( 3,4 ), and normally a slightly more moderate tip at the rear, characterised by the combination of features which are known separately, but which together form the basis for a new design with improved dynamics in special applications, which features comprise: The base is divided into a right running surface ( 2 ) and a left running surface ( 1 ). The running surfaces form an angle with each other which everywhere is less than 90 degrees. The angle which the running surfaces form with each other is smaller in the middle than at the transition to the tips, with the result that the right ( 2 ) and the left ( 1 ) running surfaces substantially form a more acute angle with each other in the transition from the narrowest cross section at the middle towards each of the tips
