Skate blade with improved properties

A skate blade (10) for skating shoes, comprising a length, a width, an external and an internal edge (2, 3), said blade (10) can be divided along its length to three adjoining regions, namely a posterior region (5), a middle region (1), and an anterior region (4), where a coordinate system with mutually normal directions x, y and z can be associated with a central plane (6) halving the blade at the middle region (1), wherein a direction x designates a distance in forward direction of an edge point, a direction y designates a lateral distance of an edge point from the central plane (6) and a direction z designates a height of an edge point from the height of the edge in the middle region (1), in which at any edge point with a coordinate x the height z of both edges (2,3) are the same, and in the middle region (1) the external and the internal edges (2, 3) are parallel, and have a zero height (z=0) and in the anterior and posterior regions (4, 5) the edges (2, 3) have a height greater than zero, and in at least one of the anterior and posterior regions (4, 5) the width of the blade (10) increases with the absolute value of the coordinate x along an arced curve, characterized in that the increase in width of the external or internal edges (2 or 3) is different from the width of the other edge (3 or 2).
