I just love how Mary slides off the shoes at :48 just to demonstrate how she puts them on

Shawn tries on the slide sandals in this video and a closeup starts at 2:16 which includes a moment of her sliding the sandal off and then putting it back on during that closeup. A bonus closeup of Jill Martin's feet includes her sliding off and on a sandal too at 4:52
