"Are your feet tired?"

Translation: 你的脚累吗？

[eric.boyang.an]

你脚累吗?
would also be understood, it is definitely more colloquial but occurs naturally in speech.

[wisnit]

Makes sense since it's clearly one's own feet

[Jamil_Paul]

Totally yes.

[Mama818045]

Isn't 很 or a similar word such as 非常 usually required before an adjective？

[ThieumL]

Not in questions.

Can someone tell me how would 足 and 脚 be different here?
Thanks.

你的脚累不累。 I wish they could just fix all of these at once.
