The radical 辶 (しんにょう) represents movement or walking. Combined with 米 (rice, used phonetically here), it forms the idea of wandering or being unsure of direction — someone who is “lost.”

道みちに 迷まよってしまいました。
I got lost on the way.

彼かれは 進路しんろに 迷まよっている。
He is unsure about his career path.

On-yomi is メイ, as in 迷信 (superstition) or 迷路 (maze). Kun-yomi is まよう, meaning to get lost or hesitate.
