Actress Cameron Diaz has designed a collection of footwear for Pour La Victoire, and says it is high on practicality.

The 42-year-old, who was announced the New York label's art director in 2013, shot her first ever campaign at the helm of the accessories brand for their spring-summer 2014 collection in May and has now released her debut footwear.

"I'm such a stickler for shoes and function. And that's what we are getting back to with this line - function,` Vogue.co.uk quoted Diaz as saying.

"When I'm in New York, I pretty much wear flats. If I get a great pair of heels that I can walk in the city in, I find myself in those heels all the time. Otherwise, if I'm in the city I wear more of a utilitarian boot."

"But in Los Angeles, because you're in your car all the time, I find myself wearing heels a lot. And I really love a good heeled boot because I move quickly on my feet and I want something that's going to stay on."

"That's why with my Pour La Victoire line you see strappy bits on some shoes because functionally you want something that looks good on the foot but stays on the foot and doesn't require a lot of work to do so,` she added.
