Simple concepts, sensitizing your feet as erogenous zone, activated through heels of your choice, the general temptation to imagine you are helplessly controlled as you put your "best foot forward". Feminization flourishes on top of that including dresses, makeup, heels, walking in ways that feel "feminine" to you, doing your hair, etc. General positivity and encouragement and fetish-building for heel-wearing and ritually getting dressed as a comfy thing to do.
