Induction heatable clothing items such as footwear ( 22 ) and apparel ( 160 ) are provided which include a clothing body having an induction heatable element ( 36, 108, 112, 114, 116 ) and preferably having heat retentive material containing phase change material, wherein the element ( 36, 108, 112, 114, 116 ) is operable to be heated when subjected to an alternating magnetic field. The clothing items ( 22, 160 ) are heated using induction heaters ( 26, 84 ). In preferred forms, wireless temperature sensing is used to control heating of the items ( 22, 160 ). To this end, the heating elements ( 36, 108, 112, 114, 116 ) may be provided with RFID tag/temperature sensor assemblies ( 58, 60, 110 ), and the induction heaters ( 26, 84 ) are equipped with correlated RFID reader/writer devices ( 80 ). Alternately, microwire temperature sensors ( 120 ) may be used with the induction heaters ( 26, 84 ) having microwire detectors. In other embodiments, temperature monitoring is achieved using impedance detection feedback control.
