🦶👟 足 foot + 登 climb = stepping on things to go up
The foot radical 足 plus 登 (to ascend) makes treading or stepping. Also used for pulling on shoes — feet step into them. Slang sense: stepping on someone means dumping them.
蹬 — foot radical 足 + 登 (climb/ascend)
A semantic-phonetic compound. The foot radical 足 supplies the meaning, since the action involves the legs, while 登 (dēng, 'to climb/step up') gives the sound and reinforces the sense of pushing upward. Together they convey pressing down forcefully with the foot, as in pedaling, kicking, or stepping hard.
