Abstract: A skate boot appliance for absorbing impact force of landing skating maneuvers by disposing a plunger or displacement member in a receptacle in response to an impact force, such that the receptacle is attached to a skate boot bottom and has a counterforce mechanism for resisting displacement below a threshold force, and resiliently deforming in response an impact force greater than the threshold force. The impact force is transferred from a skate blade through the plunger in response to a figure skating maneuver The disclosed plunger has a post and a horizontal displacement portion adapted to be disposed through the receptacle and engage the counterforce mechanism, such as the resilient planer member, in response to the threshold impact force, in which the horizontal displacement portion includes a convex ridge or protrusion for engaging the resilient planar member along an annular surface defined by the convex ridge.
