This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
蹯 combines 足 (foot) with 番, which likely contributes the sound. The exact historical development is uncertain.
The left side 足 suggests a foot, and the right side 番 looks like a numbered paw. Picture an animal's paw print, but remember the meaning is uncertain.
For ハン, imagine a half-formed paw print: half -> ハン, and the foot 足 leaves a faint mark.
