ABSTRACT:
A spike is mountable onto the sole of a spiked track shoe which allows a runner to develop maximum propulsion against the field surface. The spike is removably attachable to the track shoe and includes an elongate support plate having at one end thereof a connection hole for connection with the shoe, and a spike portion disposed at the other end. The spike portion is disposed at an obtuse angle (i.e., greater than a right angle relative to the support plate). The spike is made of metal or of synthetic resin, and the spike portion may include one or more than one spike parts. The angle between the spike portion and the support plate is preferably between 95 and 130 degrees, and more preferably between 105 and 120 degrees. The spike portion is preferably convergent towards the tip thereof, for example in the shape of a cone. The spike portion may, however, also be suitably formed into a cylindrical shape, or in a stepped cylindrical shape.
