踪 rarely appears alone in modern Chinese. It's most commonly seen in compounds: 踪迹 (zōngjì, traces), 失踪 (shīzōng, to go missing), 追踪 (zhuīzōng, to track), 行踪 (xíngzōng, whereabouts).
memory
The character has 足 (foot) on the left and 宗 (ancestor/clan) on the right — think of it as 'the footprints your ancestors left behind,' i.e., traces.
