摘要: A golf shoe sole comprising ejecting and retracting spikes, the improvement wherein said contains a high pressure liquid pump assembly in communication with plurality of housed cylinder assemblies each which contain slidable spike seal, extreme being exerted upon contained equals firmness ejected spikes. Said having shifting means four way rotatory spool valve for control ejection retraction either auto or manual mode, one two, former operating by lever reciprocating piston. The latter auto, diaphragm located on bottom soul back heel. subject to intense momentary generated weight transference from forward walking motion human wearer. An exclusively requiring only two ball, seat, stem valve. Liquid drafted balloon type reservoir, then through sequence valves, is urged via conduit housing act sliceable assembly. comprised socket, certain spring, under compression collapses within it's self, gasket threaded cylinder. has absence threads upper portion, portion smaller diameter than root existing lower portion. Thusly when unit assembled space exists accommodate flow ports positioned top. travels over top inner walls into an outer domed convex bottom, identical size shape that conventional small blind bores enabling replacement tool field. incorporates shoulder shape, bushing bore allow eject out use.
