ABSTRACT:
A sports shoe with replaceable and retractable spikes. The shoe has a sole, comprising a plurality of spikes releasably and retractably mounted in the sole, a rack and pinion member mounted in the sole and in engagement with the spikes for extending and retracting the spikes from the sole and a release member for removing the spikes from the sole. The rack and pinion member includes a rack member with a rack gear which engages a pinion member at one end of each spike. The rack gear moves linearly and imparts rotational movement to the pinion members to extend and retract each spike from the sole. The rack member further includes an actuation tab extending exterior of the sole for easy movement of the rack. The release member includes a plurality of threaded members extending into the sole and a disengaging member at the rack member, which prevents extension and retraction of the spikes so that they are removable through the threaded members. The release member further includes a disk mounted on each spike exterior and in engagement with the sole to facilitate removal of each spike through a threaded member.
