PICS: Natalia Vodianova models shoes -- in the nude!

The Russian bombshell sizzles in a new advertising campaign for footwear couturier Stuart Weitzman's Fall/Winter 2012 line.

The shoes are probably not the first thing you'll notice in these latest advertisements from Stuart Weitzman.

Intended to promote the latest collection of high-end footwear from the world-famous designer, the photographs feature sexy supermodel Natalia Vodianova in the bare essentials -- and sometimes less!

Shot by world-famous lensman Mario Testino, the classic black and white stills capture the 30-year-old mother-of-three (yes, you read right!) in a series of sultry poses.

Here she is seen in nothing but alluring knee-high boots, a hat and knickers.

Next we see her in a pair of classic stiletto pumps with a metallic heel, set off by nothing but a blazer and sheer stockings.

Tousled waves of hair falling over her face, the supermodel shows off a pair of black suede boots with what seem to be detachable button-down panels.

In this pic, Natalia drapes herself in sensual fur to complement the luxurious knee-highs on her feet.

And here she shows off her toned tummy and beautiful ankle-length boots with sparkling cuffs.
