Kristen Stewart hates wearing high-heeled shoes while she promotes "The Twilight Saga: Eclipse."

She explained, "I feel like my feet are really p**sed off at me, just because of the shoes. That's been the biggest problem." 

Meanwhile, Taylor Lautner gives his "Twilight" co-star Kristen praise for her smooching skills. He said, "She is a fantastic kisser."

"Eclipse" opens Wednesday, June 30.  The love triangle involving Bella (Stewart), Edward (Robert Pattinson), and Jacob (Lautner) heats up in the latest film.
