The spike unit is movable in an axial direction and fixed in relation to the opening so as to allow the spike unit to move together with the inner portion of the elastic diaphragm. The spike device further comprises a guiding and supporting means for guiding the axial movement of the spike unit when the inner poriton moves in relation to the outer portion. A shoe comprising the spike device is also provided, having respective lower and upper sole members.
