Shoe spike apparatus

Shoe spike apparatus comprising:

• shoe sole attachment means adapted to be secured to a sole of a shoe including a horizontally oriented anchor plate and a stabilizer shaft affixed to and downwardly and substantially perpendicularly depending from said anchor plate, said stabilizer shaft being substantially circular in cross-section;
• a snap ring socket affixed to said shoe sole attachment means, said socket including a cylindrical wall spaced from and coaxial with said stabilizer shaft, said wall defining on an interior surface an annular groove
• a snap ring receivable within said annular groove of said socket;
• and
• a spike member including a base portion defining a substantially circular opening adapted to mate with said stabilizer shaft for engaging said stabilizer shaft to prevent lateral movement of said spike member relative to said shoe sole attachment means;
• an annular groove on an exterior surface of said base portion for receiving said snap ring for locking said spike member to said socket and hence said shoe sole attachment means;
• said base portion being rotatable about said stabilizer shaft;
• and said spike member including a gripping portion for secure engagement with a footing surface when engaged therewith.
