Claim:
An article of footwear comprising: (a) a sole and a boot connected to said sole; (b) location determining means for determining the location of said footwear; (c) transmitter means for transmitting a signal encoded with said location of said footwear; (d) a covert alarm activation switch which the wearer of the footwear can selectively activate to cause said transmitter means to transmit said signal encoded with said location of said footwear; (e) automatic alarm activating means which can automatically respond to a condition indicative of the footwear being accelerated at a rate greater than normal walking, running, or driving accelerations, wherein such rate of acceleration is inconsistent with normal activity of a wearer, by causing said transmitter means to transmit said signal encoded with said location of said footwear irrespective of any manual activation of said covert alarm activation switch by the wearer of said footwear; and (f) control means for causing the transmission of the location encoded alarm signal by said footwear in response to a manual activation signal from said covert alarm activation switch or in response to an activation signal automatically generated by said automatic alarm activating means.
