Victoria Beckham is too busy to wear high heels.

The fashion designer has ditched her skyscraper stilettos in favour of a more comfortable shoes to help her cope with her hectic schedule, which involves running her business and raising her four children, Brooklyn, 15, Romeo, 12, Cruz, nine, and three-year-old Harper, with her husband David Beckham.

In an interview with The Independent newspaper, she said: ''When I first started, I used to wear a lot of tight dresses. Lots of heels. And I still do dress like that, but I suppose, as time has gone on, I've loosened up a bit.

''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.''

Former Spice Girls singer Victoria - who founded her eponymous clothing label in 2008 - also puts her change in style to developing more confidence and confessed she would have been ''scared'' to throw on her flats in the past.

The 40-year-old star said: ''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. I would have been scared to do that. Now I'm not.

''As you get older you get a different kind of confidence.''

Victoria added that like most women, she feels she has made her fair share of fashion faux-pas.

She said: ''Times change. Certain things I wore then felt right then. But it wouldn't feel right now.''
