ABSTRACT:
A self-cleaning, or anti-fouling, shoe spike structure is provided that includes an elongate normally vertical earth-engaging spike with upper and lower ends, means securing the upper end of the spike on a shoe with said spike depending from a normally downwardly disposed earth-engaging surface of the shoe and self-cleaning means comprising an annular debris-repellant barrier positioned about the upper end of the spike. The barrier may be in the form of a movable washer that projects outwardly from the spike and underlies the shoe surface. Or it may be in the form of a stationary non-wetting member surrounding the spike. The barrier operates to allow for substantially free movement of soil and other debris about the upper end of the spike and the portion of shoe surface about the spike thereby preventing accumulation and compaction of soil or other debris on the bottom of the shoe about the spike.
