Abstract

A skate with aligned wheels substantially comprising: a plurality of wheels; and a support member including on one side a bearing base to unmovably support a shoe and to contain the wheels on the other side; and travelling stabilizing means that cooperate and are connected to the support member and to a pair of wheels. Skate vibration dampening is guaranteed by the cooperation between stabilizing means and support member through resilient means; moreover, the stabilizing means are connected to support member and wheels in order to allow each one of the rotation axes of the wheels to be moved, whether separately or not with respect to the other rotation axes, vertically with respect to the ground.
