A wheel for an inline skate that may reduce rolling friction and provide a wider rolling base giving more stability. The wheel comprises a hub for receiving an axle and a wheel body defining a circumference of the wheel. The wheel body comprises a circumferential surface extending along the circumference of the wheel. The circumferential surface comprises a first contact surface and a second contact surface for being in rolling contact with a skating surface on which the inline skate moves. The wheel body also comprises a receding surface extending from the first contact surface to the second contact surface and forming a recess between the first contact surface and the second contact surface.
