She walks weird in the commercial

Same thought here, my wife says its because she is uncomfortable in heels.

It is very awkward. At first I thought that she was trying to simulate walking on ice, but it certainly wasn't working that way as a visual.

What is up with the way Kate McKinnon walks in her Verizon commercials?

There is something amiss with the SNL star in her Verizon ads, says Kelly Conaboy. "The advertisements from spring and summer showed something amiss," says Conaboy. "McKinnon approaches the screen hunched, as if she is a server at a movie theater that also offers food and cocktails, making her way to a customer’s seat. Verizon offers no explanation. When interacting with supposed Verizon customers, and walking to the left or right, McKinnon walks upright, and for a moment we are at ease...Is Kate McKinnon being made to stand in a too-small cage at Verizon headquarters while inactive? Is the job of carrying two large water buckets between takes included in her contract?"

She walked oddly in "Joe vs. Carole" but I thought she was doing it on purpose for the character. Guess not.

It's well known throughout the industry she's a slumper. Kate's nickname is Colombo 2.
