Hobbits prosthetic Ears and feet

Reading that Martin Freeman kept some souvenirs from filming the hobbit (his prosthetic ears and feet) had me thinking:

Was there any reference in the books that hobbits had pointy ears and over-sized feet?

I remember there being lines suggesting they had hairy feet, and thick soles to allow them to walk over stones. When reading the book I just assumed they had normal human feet like say Cody Lundin, someone who just walks barefoot a lot.

Are the over-sized feet created for the film so people don't think "why don't they just wear shoes?" And was there any suggestion that hobbits had ears different to humans?
