The Pistol ankle boots, designed by the Swedish label Acne, are proving the objects of desire among the world’s current It girls including Keira Knightley, Michelle Williams, Clemence Poesy and others.

The boots, which come in a variety of colors, have been photographed on the feet of many, their trademark zipper attached with leather tassel seen swinging with each starlet’s every step.

Some stars, like Dakota Fanning, have been spotted in variations of the classic black leather boot, which feature a sturdy wedge heel and stitching to create subtle panels at the front.

An almond-shaped tow toughens up the boot which also features a gunmetal-tone side zip that carries the tassel.

Dakota Fanning was spotted at LAX airport in January, wearing a camel toned pair of Pistols, which sell for $566 online at My-Wardrobe.com.

Price-wise, it is about the average one will pay for the shoe online. Net-a-Porter is selling it for $560.

Dakota Fanning’s boot featured a black wedge heel and served as a statement item beneath her brown skin-tight pants – though not as much of a statement as the pink-dipped locks she also revealed during that spotting.

A spokesman for My-Wardrobe.com said that the boots were the “fastest selling ankle boots of all time” and after stock was replenished earlier this week, the Pistol is “flying out of the door”.

Keira Knightley appears to love her boots so much that she alternates between different colors.

The Anna Karenina actress has been photographed wearing the black variety several times but has also opted for a grey suede design on other occasions.

Michelle Williams wore her own Pistols while visiting Paris in February to promote My Week With Marilyn.

Photographed leaving the Musee d’Orsay, the petite blonde paired the design with black skinny-leg jeans.

The design is also featured on various fashion blogs, no doubt a result of the design’s multiple star endorsements.

French actress Clemence Poesy wore a black pair to the Chloe collection show Paris Fashion Week last year while Olivia Wilde was also spotted wearing the boots when she attended the Tribeca Film Festival in April.

Clemence Poesy kept her look all-black, pairing the boots with a leather jacket and skin-tight pants.

Rachel Weisz was also spotted wearing the design at JKF airport in February of last year.

Carrying her son Henry, the brunette beauty opted for navy skinny jeans to complete the casual look
