Abstract
Shoe soles with and without removable/replaceable gripping pods for athletic or sport shoes are provided with enhanced traction. The sole portions or gripping pods may be provided with a supply of a substance that exhibits a tackiness for enhancing friction between the shoe sole and the any hard floor. The tackiness-enhancing substance may be time-released or discharged from within the shoe sole onto the lower surface(s) of the sole that make(s) contact with the smooth hard playing surface or may be in response to compression or shear forces acting on the sole during play to prolong the tacky properties and reduce slippage. A visual indicator may be provided for notifying the player that it is time to replace the worn or used pod and insert a fresh pod or insert into the pod(s) to maintain high levels of gripping.
