K-Swiss has signed a global endorsement deal with Jillian Michaels, the tough-as-nails trainer from "The Biggest Loser."

The Westlake Village, Calif.-based company says this is the first performance brand endorsement for Michaels, who is also set to start in a new NBC series, "Losing it with Jillian!," this summer.

Michaels has worn K-Swiss Tubes Run 100 on various TV appearances this year, a performance sneaker that features full-length cylinders for cushioning and stability.--Sarah Mahoney
