Victoria Beckham is swapping stilettos for sneakers!

In a new interview, the 40-year-old fashion designer revealed she's simply too busy to be completely glammed up all the time.

"I'm busier now — so I couldn't totter around in a tight dress and a pair of heels! I think I feel a little more relaxed," the mother-of-four said of her new style.

"I suppose if I'm being honest, I would have been scared, right at the beginning, to wear lots of layers and to wear a flat shoe. Now I'm not," Victoria added.

The former 'Spice Girls' songstress was previously known to don tight-fitting bandage dresses and sky-high heels for almost every public outing. But recently, the star has opted for a more-dressed down look with sweaters, scarves and sensible slacks.

This past Sunday, Victoria — who is married to 39-year-old soccer star David Beckham — debuted her new AW15 clothing collection at New York Fashion Week, which focused on loose-fitting pieces made for comfort.

"Times change. Certain things I wore then felt right then," she told 'The Independent.' "But it wouldn't feel right now."
