Claim:
A snowthrower skid shoe configured for use with a snowthrower, the skid shoe comprising: an elongate runner plate with an upper surface and a lower surface, where the lower surface includes: at least five contiguous lower faces configured as a first leading face, a second leading face, and intermediate face, a first trailing face, and a second trailing face; where each of the first leading face and the second trailing face is offset by a first angle, where the first angle is about 43°, from a plane continuous with the intermediate face; where each of the second leading face and the first trailing face is vertically offset by a second angle, where the second angle is about 23°, from the plane continuous with the intermediate face; where a longitudinal end terminus of the first leading face is vertically perpendicularly offset from the plane continuous with the intermediate face by about two inches; a first lateral edge defining a longitudinal side of the runner plate, where the first lateral edge is disposed opposite and generally parallel with a second lateral edge; and a mounting flange extending substantially vertically from the upper surface, the mounting flange disposed immediately adjacent one of the first lateral edge or the second lateral edge; where a transition between the first lateral edge and the second lateral edge, including the end terminus includes an asymmetrical filleted radius such that a generally rounded portion of the transition including the end terminus is latitudinally nearer to the mounting flange than to a generally straight portion of the transition.
