The runner-blade assembly may be removably attached to first and second cups that are optionally removably attached to the sole of a skate boot. The first and second cups optionally are removably attachable at multiple lateral locations on the sole. Mounting plates to which the first and second cups are mounted may be included to provide damping interfaces between the first and second cups and the boot sole. The first and second cups may be separately removable from the sole such that the first cup may be replaced with a third cup (for example, a cup having a different stiffness than the first cup) without removal of the second cup. ## Claims ### Claim 1 A hockey skate, comprising: a boot including a sole; a first cup attached to the sole, the first cup comprising a first material having first vibration-damping properties; a second cup attached to the sole, the second cup comprising a second material different than the first material, the second material having second vibration-damping properties different than the first vibration-damping properties; and a runner-blade assembly removably attached to the first and second cups. ### Claim 2 (depends on 1) The hockey skate of claim 1 wherein the runner-blade assembly comprises a runner integrated with a skate blade. ### Claim 3 (depends on 2) The hockey skate of claim 2 wherein the first cup and the second cup have different vibration-damping properties than the runner. ### Claim 4 (depends on 1) The hockey skate of claim 1 wherein at least one of the first and second cups is removably attached to the sole. ### Claim 5 (depends on 4) The hockey skate of claim 4 wherein the first cup and the second cup are separately removable from the sole such that the first cup may be replaced with a third cup without removal of the second cup. ### Claim 6 (depends on 1) The hockey skate of claim 1 wherein at least one of the first and second cups is removably attachable at multiple lateral locations on the sole. ### Claim 7 (depends on 1) The hockey skate of claim 1 wherein the runner-blade assembly has a first stiffness, and wherein the first and second cups are configured to receive runner-blade assemblies having a different stiffness than the first stiffness. ### Claim 8 (depends on 1) The hockey skate of claim 1 further comprising a first mounting plate—to which the first cup is mounted—fixed to a first end of the boot, and a second mounting plate—to which the second cup is mounted—fixed to a second end of the boot. ### Claim 9 (depends on 8) The hockey skate of claim 8 wherein the first and second mounting plates each comprise a layer of damping material. ### Claim 10 (depends on 8) The hockey skate of claim 8 wherein the first and second mounting plates are made of different materials than the first and second cups. ### Claim 11 (depends on 1) The hockey skate of claim 1 wherein the runner-blade assembly comprises a runner removably attached to a skate blade such that the skate blade is attachable to runners having different stiffness properties. ### Claim 12 (depends on 1) The method of claim 1 further comprising replacing the first cup with a third cup having different vibration-damping properties than the first cup. ### Claim 13 A hockey skate, comprising: a boot including a sole; a first cup removably attached to the sole, the first cup comprising a first material having first vibration-damping properties; a second cup removably attached to the sole, the second cup comprising a second material different than the first material, the second material having second vibration-damping properties different than the first vibration-damping properties; and a runner-blade assembly attached to the first and second cups. ### Claim 14 (depends on 13) The hockey skate of claim 13 wherein the runner-blade assembly is removably attached to the first and second cups, and the first cup and the second cup are separately removable from the sole such that the first cup may be replaced with a third cup without removal of the second cup. ### Claim 15 (depends on 13) The hockey skate of claim 13 wherein at least one of the first and second cups is removably attachable at multiple lateral locations on the sole. ### Claim 16 (depends on 13) The hockey skate of claim 13 further comprising a first mounting plate—to which the first cup is mounted—fixed to a first end of the boot, and a second mounting plate—to which the second cup is mounted—fixed to a second end of the boot, wherein the first and second mounting plates are made of a different material than the first and second cups such that they provide damping interfaces between the first and second cups and the sole. ### Claim 17 A method of changing the vibration-damping properties of a skate that includes a first runner-blade assembly attached to a first cup and a second cup, with the first and second cups attached to a sole of the skate, comprising: detaching the first runner-blade assembly from the first and second cups; and attaching a second runner-blade assembly to the first and second cups, the second runner-blade assembly having the same physical configuration as the first runner-blade assembly but having different vibration-damping properties than the first runner-blade assembly. ### Claim 18 (depends on 17) The method of claim 17 further comprising replacing the blade of the runner-blade assembly with a different blade having different vibration-damping properties.
