$10,000,000 to live as a Giantess’s insole for 1 year

A beautiful giantess offers you $10 million dollars if you agree to be shrunk to the size of an insole and live inside her high heel / sneaker / boot for one full year.

• She wears the shoe at least 8 hours every day.
• You will be pressed against her bare foot the entire time, but you are unharmed and given basic necessities to survive.
• You need to worship and massage her feet at any point she wants.
• She will occasionally acknowledge you but mostly treat you like an object.
• At the end of the year you return to normal size unharmed.

Do you accept? If yes, which type of shoe would you choose to live in (high heels, sneakers, boots, sandals, etc.) and why?
